[0047] <System Architecture>

[0048] Figure 6 This is a schematic diagram of a file transfer system framework according to one or more embodiments of this application, such as... Figure 6As shown, the file transfer system includes a mobile terminal and a display device. Files in the mobile terminal 100A are transferred to a hard disk 700 via a network. The hard disk 700 can be integrated into the display device or used as an external device connected to the display device 200. The file transfer system can be based on a wide area network (WAN) for file data transmission. The mobile terminal 100A sends the file to a server 400, so that the file stored on the server 400 awaits retrieval by the hard disk service 800 in the display device. The hard disk service 800 then transfers the retrieved file to the hard disk 700. For example, the server is an ESS server (Enterprise Storage Server). Simultaneously, the first upload progress information of the file is sent by the mobile terminal 100A to the hard disk service 800 (NasService) via a message server 500. For example, the message server can be an MQTT message server (Message Queuing Telemetry Transport). Based on the first upload progress information, the hard disk service 800 determines the file transfer progress and sends it to the preset application 900. The preset application 900 then displays the file transfer progress on the user interface. The preset application 900 and the hard disk service 800 are two processes bound together via AIDL (Android Interface Definition Language) to achieve cross-process communication.

[0049] <File Transfer Methods>

[0050] This application provides a file transfer method in some embodiments, the method including: S101, receiving an input signal from a mobile terminal to a display device for file transfer, and determining progress information. In this application embodiment, when the mobile terminal transfers a file to the display device, an input signal is sent to the display device. In some embodiments, the file in the mobile terminal is transferred to the display device connected to a hard disk by transferring the file in the mobile terminal to the hard disk via a network. Network transfer is divided into wide area network (WAN) transfer and local area network (LAN) transfer. The following will describe the two cases of WAN transfer and LAN transfer.

[0051] S102. Determine the file transfer progress based on the progress information, and control the display to show the file transfer progress. In some embodiments, the step of determining the file transfer progress based on the progress information includes: the progress information includes first upload progress information of the mobile terminal transferring a file to the server, the first upload progress information including the total file size and the size of the file already uploaded to the server. Half of the size of the file already uploaded to the server is divided by the total file size to determine the file transfer progress. In some embodiments, the mobile terminal periodically sends the first upload progress information to the display device.

[0052] In some embodiments, the process of mobile terminal 100A uploading files to a server is as follows: The mobile terminal can share files to a display device through a file-sharing application. For example, the user interface of the mobile terminal is an image display interface, with a share icon control in the lower right corner. The controller receives a user input instruction to select the share icon control and, in response to this instruction, displays a share bar overlaid on the image display interface. This share bar includes multiple application icon controls for sharing and multiple operation text controls. The controller receives a user input to select the "Home Private Cloud" application icon control and, in response to this instruction, the user interface jumps to the Home Private Cloud application interface. This interface includes a "Share to Home Private Cloud" text control. The controller receives a user input instruction to select the "Share to Home Private Cloud" text control and, in response to this instruction, jumps to the device selection interface. In some embodiments, the device selection interface includes multiple device controls: a "Living Room Display Device" device control and a "Bedroom Display Device" device control. The controller receives a user input instruction to select the "Living Room Display Device" device control and, in response to this instruction, uploads the currently displayed image to the living room display device corresponding to the "Living Room Display Device" device control. Specifically, the mobile terminal uploads the image to the living room display device via the ESS server. During the upload process, an upload progress bar, a "Sending" message, and a "Cancel" control are displayed on the screen. The mobile terminal can also cancel the image upload by selecting the "Cancel" control.

[0053] In some embodiments, a QR code on the display device related to the Home Private Cloud application can be used to open the Home Private Cloud application on a mobile device. Figure 7 This is a display interface diagram according to one or more embodiments of this application, such as Figure 7 The application interface includes "Photos and Videos" and "Other Files" controls, as well as the prompt "Select the file type you want to upload." In some embodiments, uploading files from a mobile terminal to a display device requires connecting the mobile terminal and the display device to the same Wi-Fi network or hotspot. Figure 8This is a diagram of a Wi-Fi connection display interface according to one or more embodiments of this application, such as... Figure 8 As shown, if the mobile terminal is not connected to Wi-Fi, a prompt will be displayed on the user interface: Please go to Settings - Wireless LAN - Connect to Wi-Fi or Settings - Personal Hotspot - Turn on Hotspot. After the user completes the setup according to the prompt, the controller receives the user's instruction to select the "Click Refresh" control. Responding to this instruction, if the refresh is successful, it will... Figure 8 The user interface shown jumps back Figure 7 The user interface shown.

[0054] In some embodiments, the controller receives a user's instruction to select the "Photos and Videos" control, and in response to that instruction, retrieves data from the control. Figure 7 The user interface then redirects to a file display interface, which includes multiple image and video files. Each image and video file has a checkbox in its upper right corner. The controller receives user input to select either the image or video file checkbox. In response, it fills the selected checkbox with numbers, labeling the checkboxes according to the user's selection order.

[0055] In some embodiments, when the number of images and videos selected by the user reaches a preset value, such as 6, unselected images and videos in the file display interface are displayed in gray, while selected images and videos are highlighted. The controller receives a command from the user to complete the selection control, and in response to this command, the file display interface jumps to... Figure 9 The user interface. Figure 9 This is a schematic diagram of a file transfer progress interface according to one or more embodiments of this application. The interface displays a transfer progress bar and a prompt "Uploading". The transfer progress bar shows the transfer progress of the file data determined based on the signal for transferring file data.

[0056] File transfer over a wide area network

[0057] In some embodiments, the traffic generated during file transfer between the mobile terminal and the display device over a wide area network is twice the total file size. For example, if the total file size is 100MB, the traffic generated when the mobile terminal uploads the file to the server is 100MB, and the traffic generated when the display device downloads the file from the server is also 100MB, resulting in a total traffic of 200MB for both stages. In this embodiment, half the size of the file already uploaded to the server is divided by the total file size to determine the file transfer progress.

[0058] In some embodiments, the file transfer progress is displayed as a percentage, ranging from 0% to 100%. Therefore, the file transfer progress corresponding to the complete transfer of the file from the mobile terminal to the server is 50%, and the file transfer progress corresponding to the transfer from the server to the display device is also 50%. In this embodiment, when the mobile terminal transfers the file to the server, the file transfer progress displayed on the interface can be obtained by dividing half the size of the file already uploaded to the server by the total file size. For example, if the size of the file already uploaded to the server is 80MB and the total file size is 100MB, then the file transfer progress is 80 * 0.5 / 100 = 40%. In other embodiments, the file transfer progress can be determined by dividing the size of the file already uploaded to the server by twice the total file size. For example, if the size of the file already uploaded to the server is 80MB and the total file size is 100MB, then the file transfer progress is 80 / (100 * 2) = 40%.

[0059] In some embodiments, after the mobile terminal has completely uploaded the file to the server, the progress information includes download progress information of the display device downloading the file from the server; the download progress information includes the total file size and the size of the file already downloaded to the display device; the file transfer progress is determined by adding half of the total file size and half of the size of the file already downloaded to the display device, and then dividing by the total file size. Since the mobile terminal has already transferred the entire file to the server when the display device downloads the file from the server, the file transfer progress can be determined by adding half of the total file size and half of the size of the file already downloaded to the display device, and then dividing by the total file size. For example, if the size of the file already downloaded to the display device is 80M and the total file size is 100M, then the file transfer progress is (100 / 2 + 80 / 2) / 100 = 90%.

[0060] In other embodiments, the file transfer progress can be determined by adding the total file size to the file size already downloaded to the display device and then dividing by twice the total file size. For example, if the file size already downloaded to the display device is 80M and the total file size is 100M, then the file transfer progress is (100+80) / (100*2)=90%.

[0061] In some embodiments, the file transfer progress can also be displayed on the display interface in other ways. For example, in the first stage of the mobile terminal uploading a file to the server, the size of the file already uploaded to the server is 80M, and the total file size is 100M. At this time, the file transfer progress can be displayed as 40M / 80M, where 40M is half of the size of the file already uploaded to the server.

[0062] In some embodiments, prior to the step of determining progress information, the method further includes: receiving basic information about a file sent by a mobile terminal and displaying a notification message on a user interface. Figure 10 This is a diagram of a notification message interface according to one or more embodiments of this application, such as... Figure 10 As shown, the notification message 801 is displayed in the upper right corner of the user interface, which prompts the user that the mobile terminal is transferring files to the display device. In some embodiments, the notification message also includes prompts displaying a detailed list, for example... Figure 10 In this context, the prompt message for displaying the detailed list indicates that you should press the menu button to view it.

[0063] In some embodiments, Figure 11 The diagram shows a display interface according to one or more embodiments of this application. When a user presses the menu button on the control device, the user interface displays as follows: Figure 11 As shown, the user interface displays a detailed file list 901, which shows basic information about one or more files. In some embodiments, the basic file information includes information such as file name, total file size, and file type. In some embodiments, when the file transfer progress reaches 100%, a message indicating successful file transfer will be displayed on the interface.

[0064] In some embodiments, the mobile terminal sends basic file information to a hard disk service via a message server. Upon receiving this basic file information, the hard disk service sends it to a preset application, which then displays a notification message on its user interface. In some embodiments, the file transfer progress may be displayed in the notification message and / or a detailed file list.

[0065] File transfer within a local area network

[0066] In some embodiments, the mobile terminal is connected to the display device via a local area network, and the controller performs the step of determining the file transfer progress based on the progress information according to the following steps: the progress information includes second upload progress information of the mobile terminal transferring files to the display device; the file transfer progress is determined based on the second upload progress information. In some embodiments, refer to Figure 6 Mobile terminal 100A sends a file and second upload progress information to hard disk service 800 through web server 600. Hard disk service 800 transfers the file to hard disk 700, determines the file transfer progress based on the second upload progress information, and sends it to the preset application 900 for display. Mobile terminal 100A can directly transfer files to hard disk 700, so the traffic generated in the entire process is the total file size. For example, if the total file size is 100MB, the traffic generated is 100MB.

[0067] In some embodiments, the controller is configured to perform the following steps to determine the file transfer progress based on the second upload progress information: when the number of files is one, the second upload progress information includes the total file size and the file size already transferred to the display device; the file size already transferred to the display device is divided by the total file size to determine the file transfer progress. For example, if the file size already transferred to the display device is 80MB and the total file size is 100MB, then the file transfer progress is 80 / 100 = 80%. In other embodiments, the file transfer progress can be displayed as 80MB / 100MB, which allows users to intuitively understand the total file size and the file size already transferred to the display device.

[0068] When the number of files is greater than one, the second upload progress information includes the total number of files and the number of files already transferred to the display device; the file transfer progress is determined based on the total number of files and the number of files already transferred to the display device. For example, if the number of files already transferred to the display device is 8 and the total number of files is 10, then the file transfer progress can be 8 / 10 = 80%. In other embodiments, the file transfer progress can be displayed as 8 / 10, which allows users to intuitively understand the total number of files and the number of files already transferred to the display device.

[0069] Space Management

[0070] In some embodiments of this application, connecting the hard disk to the display device can expand the available memory space of the display device, preventing performance issues caused by insufficient memory space. Since the hard disk may not be pre-connected during display device setup, it's possible that the display device is initially used without a hard disk connection, and the memory stores local files. To avoid insufficient memory space, embodiments of this application propose a solution to cut and paste local files from the memory to the hard disk, preventing the memory from becoming too small. Some embodiments of this application provide a file transfer method, comprising: receiving an instruction to transfer local files to the hard disk, and cutting and pasting the local files to the hard disk.

[0071] In some embodiments of this application, "native files" can refer to data generated by the display device itself or data generated by third-party applications running on the display device. Of course, other data occupying the display device's memory can also be stored on the hard drive. It should be noted that in the embodiments of this application, when the display device is not connected to the hard drive, the native files are stored in the memory; when the hard drive is connected to the display device, all native files are stored on the hard drive.

[0072] In some embodiments, a user can determine whether to cut and paste native files from storage to hard disk after viewing the available space on the display device. To avoid the user having to view the available space on the display device, before receiving an instruction to transfer native files to the hard disk, the method further includes: receiving an instruction to display the available space on the display device, controlling the user interface to display the space on the storage and hard disk, and providing a one-click import control on the user interface.

[0073] Since the instruction to display the usage space of the display device occurs when the hard drive is not initially connected to the display device but is connected after the display device is put into use, the user interface displays the storage and hard drive space. Additionally, for user convenience, a one-click import control is also displayed on this user interface. For example, Figures 12-18 To receive instructions on displaying the display device's usage space according to one or more embodiments of this application, the user can move the selector to the desired location using the display device via a control device. Figure 12 The user interface displays the space management control 601, and the user presses the confirmation button on the control device to complete the process. The user interface then redirects as follows: Figure 13 As shown, Figure 13 The user interface displays memory space usage 701 and hard disk space usage 702. Figure 13 The user interface also displays a one-click import control 703 and a hard disk expansion control 704.

[0074] In some embodiments, the space management control also displays the used space of the memory or hard disk; it should be noted that a control refers to a visual object displayed in the GUI of a display device to represent corresponding content such as icons, thumbnails, video clips, links, etc. The display form of controls is usually diverse. For example, a control may include text content and / or an image used to display thumbnails related to the text content. Another example is that a control may be text and / or an icon of an application. It should also be noted that a selector is used to indicate that any of the controls has been selected, such as a focus object. On the one hand, a control can be selected or controlled by the user controlling the movement of the focus object displayed on the display device through input from the control device. For example, the user can use the arrow keys on the control device to control the movement of the focus object between controls to select and control the control. On the other hand, the focus object can be selected or controlled by the user controlling the movement of each control displayed on the display device through input from the control device. For example, the user can use the arrow keys on the control device to control the movement of each control simultaneously to select and control the control while keeping the position of the focus object unchanged. The identification form of selectors is usually diverse. For example, such as... Figure 12The position of the focused object can be identified by changing the border line, size, color, transparency, outline and / or font of the text or image of the focused control, or by setting the background color of the control.

[0075] In some embodiments, the following scenario may also occur: the hard drive is connected to the display device when the display device is not in use, so that all data in the display device is directly stored on the hard drive. An instruction to display the available space on the display device is received, and the user interface displays the available space on the hard drive. For example, the user moves the selector to... Figure 12 The space management control 601 in the middle, and press the confirmation key on the control device, the user interface displaying the device's used space status, such as Figure 14 As shown, Figure 14 The system displays the hard drive space usage information (801a). Figure 14 The user interface also features a hard drive expansion control. When the user moves the selector to the hard drive expansion control using the control device and presses the confirmation button on the control device, the user interface jumps to the link to purchase hard drive expansion.

[0076] In some embodiments, native files are stored in several preset directories. When an instruction to display the usage controls of the display device is received, the system checks whether files exist in the preset directories. If files exist, the user interface displays as shown below. Figure 12 As shown, if the file does not exist, the user interface displays as follows: Figure 14 As shown.

[0077] In some embodiments, when no hard disk is connected to the display device, all data in the display device is stored in memory. Upon receiving an instruction to use the display device's storage space, the user interface displays the available memory space. For example, the user moves the selector to... Figure 12 The space management control 601 is in the middle, and the confirmation key on the control device is pressed. The user interface jumps to the following. Figure 15 As shown, Figure 15 The memory space usage is displayed in 901a. Figure 15 The user interface can also include a hard drive expansion control, allowing users to purchase a hard drive to expand the space available for their display device.

[0078] In some embodiments, the instruction to transfer native files to a hard disk, exemplarily, is... Figure 13 The selector can be moved to the one-click import control 703 via the control device, and the confirmation button in the control device can be pressed to complete the process. At this point, the local file in the memory is cut and pasted to the hard drive, and the user interface is as follows: Figure 16 As shown.

[0079] In some embodiments, upon receiving an instruction to transfer local files to the hard disk, the system first traverses the files in a preset directory and copies each file to its corresponding hard disk folder directory. If the corresponding folder does not exist on the hard disk, it creates the folder first, then performs the copying operation, and finally deletes the local files from the original storage path. The folders on the hard disk can be created based on the local file type or other attributes of the local files; no specific restrictions are imposed here.

[0080] In some embodiments, for ease of user operation, a cancel import control 1001 is displayed on the user interface, for example, such as... Figure 16 As shown. In some embodiments, receiving an instruction to select the deselect control writes the currently cutting native file to the hard disk and deletes the native file from storage. For example, in... Figure 16 In this process, the user moves the selector to the cancel import control 1001 using the control device and presses the confirmation button on the control device. The user interface displays as follows: Figure 17 As shown, when pausing the import of local files to the hard drive, the local files currently in the cutting process need to be completely written to the hard drive, and the local files in the storage need to be deleted before stopping the thread to avoid file loss. For example, the local files in the storage have been deleted, but the local files have not been written to the hard drive. Or, there may be a problem of duplicate files. For example, the local files in the storage have not been deleted, but the local files have been written to the hard drive.

[0081] In some embodiments, after selecting the Cancel Import control, the user interface that is redirected also displays a retry control. In some embodiments, upon receiving an instruction to select the retry control, the transfer of the local file to the hard drive continues. For example, in... Figure 17 The interface displays a retry control 1101. The user moves the selector to the retry control via the control terminal and presses the confirmation button on the control device to continue cutting and pasting the remaining native files that were not previously cut to the hard drive. In some embodiments, the user interface displaying the retry control also displays import result information, such as... Figure 17 As shown, the import result information indicates 5 files were successfully imported and 0 failed. In some embodiments, when all local files are cut and pasted to the hard drive, the import result information may also indicate successful import. During the process of transferring local files from the storage to the hard drive, the user exits to a user interface displaying space usage information; for example, exiting to a user interface displaying control management controls, such as... Figure 18 The user interface shown depicts a situation where, when the user moves the selector to a picture in the family dynamics and presses the menu button on the control device, the user interface displays a prompt to delete a file. For example,... Figure 18 As shown, the file deletion prompt indicates that the file is being imported and deletion and export operations are not currently supported.

[0082] In some embodiments, during the transfer of native files from storage to hard disk, the display device is detached from the hard disk. At this point, the current thread is stopped, i.e., the transfer of native files to the hard disk is stopped. The user interface displaying the hard disk space usage is refreshed. After the refresh, the user interface no longer displays the hard disk space usage, but instead displays the storage space usage. For example, during the transfer of native files to hard disk, for example... Figure 16 As shown, the display device is now separated from the hard drive, and the user interface changes as follows. Figure 14 As shown.

[0083] <Cut or copy file>

[0084] In some embodiments, files on a display device connected to a hard drive can also be cut or copied to an external storage device, such as a USB flash drive. The process of cutting or copying files from a display device connected to a hard drive to an external storage device includes:

[0085] The system receives user input to copy or cut files to an external storage device, displays all copied or cut files on the user interface, and sends the files to the external storage device. For example, the user can input a command to copy or cut files to an external storage device via a control device, in which case all copied or cut files are displayed on the user interface. The system obtains information about the files being written to the external storage device, determines the file transfer progress, and controls the display to show the file transfer progress and a prompt message indicating a detailed list. The prompt message indicating the detailed list can be viewed by pressing the menu button.

[0086] In some embodiments, when an external storage device saves a file, the display device obtains information about the files written to the external storage device. The step of determining the file transfer progress includes: when the number of copied or cut files is one, the information about the files written to the external storage device includes the total file size and the size of the files already written to the external storage device; the file transfer progress is determined based on the total file size and the size of the files already written to the external storage device. For example, the file transfer progress can also be represented using a progress bar, where the maximum value in the progress bar is the total size of the uploaded files, and the currently displayed value is the size of the files already written to the external storage device. When the number of copied or cut files is greater than one, the information about the files written to the external storage device includes the total number of files and the number of files already written to the external storage device; the file transfer progress is determined based on the total number of files and the number of files already written to the external storage device. For example, the file transfer progress can be represented using a progress bar, where the maximum value in the progress bar is the total number of uploaded files, and the currently displayed value is the number of files already written to the external storage device. In some embodiments, when all files are successfully written to the external storage device, a success message is displayed on the user interface.

[0087] In some embodiments, if it is detected that the external storage device is not connected to the display device during the process of writing files to the external storage device, a message indicating that the external storage device does not exist is displayed on the user interface. In some embodiments, if it is detected that the memory of the external storage device is full, and not all files are written to the external storage device, a message indicating that the external storage device is out of space is displayed on the user interface.

[0088] In some embodiments, background operation is supported during the transfer of native files from storage to the hard disk, allowing the transfer to continue even after exiting the user interface displaying space usage. Simultaneously, downloading files from the cloud drive to the display device is supported, as well as importing and exporting to external storage devices. Figures 19-33 This is a schematic diagram of a file cutting or copying interface for one or more embodiments of this application. Figure 19 As shown, Figure 19 The screen displays the files in the cloud drive. The user presses the menu button on the control device, and the user interface displays as follows: Figure 20 As shown. In Figure 20 The user moves the selector to the download TV control 1401 and presses the confirmation button on the control device to download the file from the cloud drive to the display device. For example, the external storage device can be a USB flash drive.

[0089] In some embodiments, when a native file is stored on the hard disk, if a native file with the same name already exists in a directory on the hard disk, the native file being stored on the hard disk can be renamed. For example, if the file in the directory is named 345, the file name corresponding to the file being stored on the hard disk can be 345(1), and it will be stored in the directory with the name 345(1). In some embodiments, if a file error is encountered during the transfer of a native file to the hard disk, a file error message will be displayed on the user interface. The file with the error can be automatically skipped to continue the transfer of other files. In other embodiments, the option to skip the file with the error can be automatically selected.

[0090] Some embodiments of this application also provide another file transfer method, including: receiving an instruction to export a file to an external storage device, and importing the file into the external storage device. The hard disk can not only store files provided by other devices, but also export files to other devices. For example, files on the hard disk can be exported to an external storage device.

[0091] In some embodiments, a one-click send control can be set on the user interface. The user can select the one-click send control through the control device and press the confirmation button on the control device to directly export the file to the external storage device. In some embodiments, the user can select a portion of the files on the hard drive to transfer to the external storage device. For example, before receiving the instruction to export files to the external storage device, the user can also select the files to be transferred to the external storage device on the user interface.

[0092] In some embodiments, selectable files on the hard drive that can be exported to an external storage device can be displayed on the screen in the following manner: when entering the home shared file browsing interface, files are sorted in ascending order of proximity, with folders displayed first. If the file is an image, such as... Figure 21 As shown, the image does not display the file name, but instead shows a thumbnail. If the file is a video, such as... Figure 22 As shown, in addition to displaying the file name, the video also displays a thumbnail. If the file is music, such as... Figure 23 As shown, the music file name is displayed. If the file is a document, such as... Figure 24 As shown, the document displays the file name. Figure 25 As shown, all files are displayed hierarchically by folder. Upon entering a file, the file path information is displayed. If the path exceeds a certain length, an ellipsis is used, for example: "...folder1>long folder name...>folder3>long folder name...". Figure 26 As shown, files can be bookmarked, and bookmarked files will be displayed in the bookmarks. Bookmarked files have a bookmark icon in the lower right corner for easy identification by users.

[0093] Users can select files to be transferred to external storage devices via the user interface and operate them through the controller's user interface. When displayed... Figure 21 When accessing the user interface, press the menu button on the control device to display, as shown below. Figure 27 The user interface is shown. The user moves the selector to the USB flash drive export control 2101 using the control device and presses the confirmation button on the control device to jump to the following... Figure 28 The user interface shown. Figure 28 In the process, users can select the files they want to transfer. When displayed... Figure 29 When accessing the user interface, press the menu button on the control device to display, as shown below. Figure 29 As shown in the user interface, the user moves the selector to the USB flash drive export control 2301 using the control device and presses the confirmation button on the control device to jump to the following... Figure 30 The user interface shown. Considering the large size of video files, the number of options for importing different video file types can be preset. For example, such as... Figure 30 In the user interface shown, a maximum of two video files can be selected. The instruction to receive the selected files, exemplarily, is... Figure 30 Users can select the video on the user interface using a selector.

[0094] In some embodiments, before importing the file to an external storage device, the user interface can view the storage device information of the external storage devices that the hard drive can send files to, making it easier for the user to select the external storage device to which the file needs to be imported. For example, as shown... Figure 28 As shown, when the user moves the selector to the export control 2201 and presses the confirmation key on the control device, if two external storage devices are inserted into the display device, the user interface jumps to the following... Figure 31 As shown.

[0095] In some embodiments, if no external storage device is plugged into the display device, the process jumps to... Figure 32 The user interface is shown below. When the user inserts an external storage device into the display device, the user can select to refresh the device control 2601 and press the confirmation button on the control device. When two external storage devices are inserted, the user interface appears as follows: Figure 31 As shown. When two external storage devices are unplugged from the display device, for example, selecting... Figure 31 The user interface shown displays a refresh device control 2501, which redirects the user interface to... Figure 32The user interface is described above. In some embodiments, after the user selects the external storage device to save the file, the file can be directly transferred to the external storage device. In some embodiments, after the user selects the external storage device to save the file, they can also select the method of file transfer; in some embodiments, files on the hard drive can be transferred directly by cutting and pasting; in other embodiments, files on the hard drive can be transferred directly by copying and pasting. For example, in... Figure 31 In the process, the user can move the selector to any USB device control using the control device and press the confirmation button on the control device to jump to, for example, Figure 33 The user interface shown has a move control 2701 and a copy control 2702.

[0096] In some embodiments, an instruction to select a move control is received to cut and paste files to the external storage device. When the user moves the selector to the move control using the control device and presses the confirmation button on the control device, the files on the hard drive are cut and pasted to the external storage device. An instruction to select a copy control is received to copy files to the external storage device. Figure 33 In addition, users can move the selector to the copy control via the control device and press the confirmation button on the control device to copy the files from the hard drive to the external storage device.

[0097] In some embodiments, during the process of exporting files from the hard drive to an external storage device, it is necessary to monitor in real time whether the external storage device is still connected to the display device. If the external storage device is removed, the export task is stopped, and the user is notified that the external storage device has been removed. The file export process involves iterating through the list of files to be exported, reading the path of each file from the selected file list information, and exporting it to the specified file directory on the external storage device. During the export process, if an export error occurs, it is also checked whether the external storage device is still connected to the display device. If it is not connected, the export failure is due to the removal of the external storage device, and a corresponding prompt is given; in this case, it is not necessary to continue iterating. If it is connected, it is checked whether the remaining space on the external storage device is less than the size of the currently exported file. If it is less, an error is caused by insufficient space on the external storage device, and a prompt is given, and the export continues to the next file. For other cases, only an export failure prompt is given, and the file list is iterated through again to continue exporting files.

[0098] Some embodiments of this application provide a method for transferring local files from a memory to a hard disk, and a method for transferring files from a hard disk to an external storage device. In this process, steps such as how to select files, how to select external storage devices, and other steps can be omitted or their order can be changed, as long as the file transfer result of this application is achieved. Furthermore, in some embodiments, the order and method of pressing the buttons to send commands via the control device are not specifically limited. In some embodiments, a specific button can be set in the control device so that pressing the button will start the file transfer. For example, when a user presses the button, the local file in the memory begins to be transferred to the hard disk.

[0099] In some embodiments of this application, in addition to exporting files from a hard disk to an external storage device and exporting local files from the storage of a display device to a hard disk, as mentioned above, this application also provides a file transfer method, including: receiving an instruction to export files from an external storage device to a hard disk, and importing the files from the external storage device to the hard disk, wherein the external storage device is connected to a display device. In some embodiments, a user can send an instruction to export files from an external storage device to a hard disk via buttons on a control device. In this case, all files in the external storage device can be directly sent to the hard disk, or the files in the external storage device can be displayed on a user interface, and the user can select the files they wish to transfer before proceeding with the transfer. In some embodiments, after the user selects the files to be transferred by the system, a transfer method can be selected, such as cut or copy.

[0100] In the above embodiments, a file transfer method and a display device utilize the storage function of a hard disk to free up storage space in a memory, thereby improving the user experience when using the display device. The method includes: receiving an instruction to transfer a local file to the hard disk; cutting and pasting the local file into the hard disk; wherein the hard disk is connected to the display device after the display device has been used.

[0101] For ease of explanation, the above description has been provided in conjunction with specific embodiments. However, the discussion in some embodiments above is not intended to be exhaustive or to limit the embodiments to the specific forms disclosed above. Various modifications and variations can be obtained based on the above teachings. The selection and description of the above embodiments are for the purpose of better explaining the principles and practical applications, thereby enabling those skilled in the art to better utilize the embodiments and various different variations of the embodiments suitable for specific application considerations.
