[0074] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION
[0075] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.
[0076] It should be noted that in the embodiments of the present application, certain software, components, models and other existing solutions in the industry may be mentioned, and they should be regarded as exemplary. Their purpose is only to illustrate the feasibility of implementing the technical solution of the present application, but it does not mean that the applicant has or will necessarily use the solution.
[0077] For ease of understanding, the following Figure 1 , briefly describe the application scenarios to which the embodiments of the present application are applicable.
[0078] Figure 1 This is a schematic diagram of an application scenario provided by the embodiment of this application. Figure 1 , including a host computer 11 and an electronic device 12 , the host computer 11 and the electronic device 12 are connected via a USB interface 13 , and information exchange can be performed between the host computer 11 and the electronic device 12 based on the USB interface 13 .
[0079] The host computer 11 may be a mobile phone, computer or other device supporting the MTP protocol; the electronic device 12 may be a mobile phone, computer, USB memory, mobile hard disk or other device connected to the host computer 11 via a USB interface 13 .
[0080] At least one folder is stored in the electronic device 12. For any folder, the folder may include files or subfolders. After the electronic device 12 is connected to the host computer 11 via the USB interface 13, the files and folders stored in the electronic device 12 can be displayed through the file management interface of the host computer 11.
[0081] When it is necessary to move the first file object in the electronic device 12, the host computer 11 can send a file move command to the electronic device 12 according to the MTP protocol. After receiving the file move command sent by the host computer 11, the electronic device 12 moves the first file object from the source folder to the target folder and sends a file move response to the host computer 11, thereby realizing the movement of the first file object. The first file object can be a file in the source folder or a subfolder in the source folder.
[0082] by Figure 1 For example, the electronic device 12 stores folder A and folder B, wherein folder A includes files 1 and 2, and folder B includes files 3 and 4. If file 2 is to be moved from folder A to folder B, the host computer can send a file move command to the electronic device according to the MTP protocol, and the electronic device moves file 2 from folder A to folder B after receiving the file move command.
[0083] It should be noted that Figure 1 This is just an example to illustrate an application scenario, and is not intended to limit the application scenario.
[0084] In the related technology, when it is necessary to move the first file object (which can be a file or folder) in an electronic device from a source folder to a target folder, the host computer sends a file move command to the electronic device according to the MTP protocol. After receiving the file move command, the electronic device reads the first file object in the source folder according to the file move command, writes the read first file object into the target folder, and deletes the first file object in the source folder, thereby completing the movement of the first file object and sending a file move response to the host computer.
[0085] However, in the above method, after receiving the file move command, the electronic device needs to perform a series of operations such as reading, writing, and deleting on the first file object, resulting in low efficiency in moving the first file object. Secondly, due to the read and write speed of the hardware device, in order to avoid the host computer receiving the move response timeout, the size of the first file object will also be limited during the process of moving the first file object through this method.
[0086] Based on this, an embodiment of the present application provides a file management method. After receiving a file move command, the electronic device can move the file or folder without performing read, write, or delete operations in the electronic device, thereby improving the efficiency of moving the file or folder.
[0087] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.
[0088] Figure 2 A flowchart of a file management process provided by an embodiment of the present application. Figure 2 , the method is applied to an electronic device, comprising:
[0089] S201. Receive a file move command for a first file object, where the first file object is initially located in a source folder, and the file move command is used to instruct to move the first file object from the source folder to a target folder.
[0090] The first file object can be any file or folder stored in the electronic device, the source folder is the folder where the first file object is currently located, and the target folder is the folder where the first file object is located after the first file object is moved, that is, when the electronic device completes the movement of the first file object, the first file object is located in the target folder.
[0091] The file move command is sent from the host computer to the electronic device, and the file move command may include identification information of the first file object and path identification information of the target folder. The identification information of the first file object is used to uniquely identify the first file object in the host computer, and the path identification information of the target folder is used to uniquely identify the storage path of the target folder in the electronic device in the host computer.
[0092] S202: Based on the file move command, determine a first storage path of the file object in the source folder in the electronic device and a second storage path of the file object in the target folder in the electronic device.
[0093] The first storage path is used to represent the file directory corresponding to the file object in the source folder in the electronic device. For example, assuming that the source folder is located in folder 1, and folder 1 is located in folder 2, the file directory corresponding to the file object in the source folder in the electronic device is source folder-folder 1-folder 2, and the first storage path is determined to be source folder-folder 1-folder 2.
[0094] Since the first file object is located in the source folder, the source folder where the first file object is located can be determined according to the identification information of the first file object in the file move command, and then the first storage path can be determined.
[0095] Similarly, the second storage path is used to represent the file directory corresponding to the file object in the target folder in the electronic device. The electronic device can determine the second storage path of the first file object in the electronic device according to the identification information of the target folder in the file move command.
[0096] S203: Update the MTP management information based on the first storage path and the second storage path, wherein, for the first file object, the updated MTP management information indicates that the storage path of the first file object in the electronic device is the second storage path.
[0097] The electronic device stores MTP management information, and the MTP management information is used to indicate the storage path of each file object in the electronic device. The MTP management information may include the storage path of at least one file object in the electronic device, and when the file object in the MTP management information is a file, the file object is represented by the file tag information of the file, and when the file object in the MTP management information is a folder, the file object is represented by the path tag information of the folder.
[0098] For any file in an electronic device, the electronic device stores the tag information of the file, which is used to uniquely identify the file; the host computer also stores the identification information of the file, which is used to uniquely identify the file, and the tag information and identification information of the file may be inconsistent. For any folder in an electronic device, the electronic device stores the path tag information of the file, which is used to uniquely identify the storage path of the folder in the electronic device; the host computer also stores the path identification information of the folder, which is used to uniquely identify the storage path of the folder in the electronic device, and the path tag information and path identification information of the folder may be inconsistent.
[0099] For example, assuming that the electronic device stores file 1, file 2, and file 3, wherein the tag information of file 1 is X, the tag information of file 2 is Y, and the path tag information of folder 3 is Z; the storage path of file 1 is folder A-folder B, the storage path of file 2 is folder A-folder C, and the storage path of folder 3 is folder D-folder E, the MTP management information may be as shown in Table 1:
[0100] Table 1
[0101] Label information / path label information The storage path of the file X Folder A - Folder B Y Folder A - Folder C Z Folder D - Folder E
[0102] The host computer can determine the storage path of the file object in the electronic device according to the storage path corresponding to the file object indicated by the MTP management information. For example, for the first file object, the MTP management information indicates that the storage path of the first file object in the electronic device is folder A-folder B, and the host computer determines that the storage path of the first file object in the electronic device is folder A-folder B according to the MTP management information.
[0103] Therefore, the file object can be moved by updating the MTP management information. Specifically, the electronic device updates the MTP management information according to the first storage path and the second storage path, and the updated MTP management information indicates that the storage path of the first file object is the second storage path, thereby moving the first file object to the target folder.
[0104] In the file management method provided by the embodiment of the present application, an electronic device receives a file move command for a first file object, determines a first storage path of a file object in a source folder in the electronic device and a second storage path of a file object in a target folder in the electronic device according to the file move command, and changes the storage path of the first file object in the MTP management information from the first storage path to the second storage path according to the first storage path and the second storage path, thereby moving the first file object from the source folder to the target folder. The movement of the first file object is completed by the above method, and there is no need to perform read, write, and delete operations on the first file object, which improves the efficiency of moving the first file object. Furthermore, since there is no need to perform read and write operations on the first file object in the above process, in the process of moving the first file object from the source folder to the target folder, it is not affected by the read and write speed of the hardware device, and there is no limit on the file size of the first file object, which improves the flexibility of moving the first file object.
[0105] exist Figure 2 Based on the embodiment shown, the following Figure 3 The process of determining the first storage path and the second storage path is described in detail.
[0106] Figure 3 A schematic diagram of a process for determining a first storage path and a second storage path provided in an embodiment of the present application. Figure 3 , the method may include the following steps:
[0107] S301: Acquire identification information of a first file object and path identification information of a target folder based on a file move command.
[0108] The file move command may include identification information of the first file object and path identification information of the target folder. The identification information of the first file object is used to uniquely identify the first file object in the host computer. The path identification information of the target folder is used to uniquely identify the storage path of the target folder in the electronic device in the host computer.
[0109] After receiving the file move command, the electronic device may obtain identification information of the first file object and path identification information of the target folder contained in the file move command based on the file move command.
[0110] Optionally, if the electronic device includes two or more memories, and the source folder and the target folder are stored in two different memories, the file move command may also include the memory identification information of the target memory. The target memory is the memory where the target folder is located. The memory identification information of the target memory is used to uniquely identify the target memory in the host computer.
[0111] Optionally, if the file move command also includes storage identification information of the target storage, the electronic device may further obtain the storage identification information in the file move command after receiving the file move command.
[0112] S302: Determine a first storage path based on identification information of the first file object.
[0113] After acquiring the identification information of the first file object, the electronic device parses the identification information of the first file object to obtain tag information of the first file object, where the tag information of the first file object is used to uniquely identify the first file object in the electronic device.
[0114] The electronic device determines the first storage path in the MTP management information according to the tag information of the first file object.
[0115] For example, assuming that the first file object is a file, and the tag information of the file is Z, the MTP management information is as shown in Table 2
[0116] Table 2
[0117] Label information / path label information The storage path of the file X Folder A - Folder B Y Folder A - Folder C Z Folder D - Folder E
[0118] According to the tag information Z of the first file object, it is determined in the MTP management information that the storage path corresponding to the first file object in the electronic device is folder D-folder E, and the storage path folder D-folder E is determined as the first storage path.
[0119] S303: Determine a second storage path based on the path identification information of the target folder.
[0120] After the electronic device obtains the path identification information of the target folder, it parses the path identification information of the target folder to obtain the path tag information of the target folder, where the path tag information is used to uniquely identify the storage path of the target folder in the electronic device.
[0121] According to the path tag information of the target folder, the second storage path is determined in the MTP management information.
[0122] For example, assuming that the path label information of the target folder is X, the MTP management information is shown in Table 3:
[0123] Table 3
[0124] Label information / path label information The storage path of the file X Folder A - Folder B Y Folder A - Folder C Z Folder D - Folder E
[0125] According to the path label information X of the target folder, the storage path corresponding to the target file in the electronic device is determined in the MTP management information as folder A-folder B; combined with the storage path folder A-folder B and the target folder, the second storage path is determined as target folder-folder A-folder B.
[0126] exist Figure 3 In the illustrated embodiment, based on the identification information of the first file object and the path identification information of the target folder in the file move command, the label information of the first file object and the path label information of the target folder are determined respectively, and the first storage path and the second storage path are determined in combination with the MTP management information. This method does not require the first file object to be read, written, or deleted, thereby improving the efficiency of file movement for the first file object.
[0127] Based on the above embodiments, Figure 4 The process of updating MTP management information is described in detail.
[0128] Figure 4 A schematic diagram of a process for updating MTP management information provided in an embodiment of the present application. Figure 4 , the method may include:
[0129] S401: Update the storage path of a first file object in an electronic device from a first storage path to a second storage path, wherein the first file object after the updated storage path is located in a target folder.
[0130] The electronic device may also include a file management system, which is used to manage the storage paths of all file objects stored in the electronic device. The file management system may provide an external interface function, through which the content in the file management system may be modified or updated.
[0131] The method of updating the storage path of the first file object in the electronic device from the first storage path to the second storage path is as follows:
[0132] Based on the first storage path and the second storage path, a command parameter of a rename function is generated; based on the command parameter, the rename function is called to update the storage path of the first file object in the electronic device from the first storage path to the second storage path.
[0133] The renaming function may be an interface function provided by the file management system to change the file name or the file storage path name, that is, to change the name of the file or the file storage path from the source name to the target name. The renaming function may contain parameters (source name, target name). For example, the renaming function may be the rename function.
[0134] The command parameter is used to indicate the parameters included in the rename function. For example, if the parameters included in the rename function are (source name, target name), the command parameter of the rename function is (source name, target name).
[0135] For the first file object, it is necessary to call a rename function to change the storage path of the first file object in the electronic device from the first storage path to the second storage path. Therefore, it can be determined that the command parameter of the rename function can be (first storage path, second storage path) according to the first storage path and the second storage path. Based on the command parameter, after calling the rename function, the rename function changes the storage path of the first file object in the electronic device from the first storage path to the second storage path.
[0136] S402: When the first file object is located in the target folder, update the MTP management information based on the first storage path and the second storage path.
[0137] The MTP management information is obtained based on the mapping of the file management system. After the storage path of the first file object in the electronic device is updated in the file management system, the electronic device changes the storage path of the first file object in the MTP management information according to the first storage path and the second storage path, that is, the storage path of the first file object in the MTP management information is changed from the first storage path to the second storage path.
[0138] For example, assuming that the first file object is a file, the tag information of the file is Y, and the MTP management information is as shown in Table 4:

[0140] Label information / path label information The storage path of the file Y Source folder-Folder A-Folder B
[0141] The first storage path is source folder-folder A-folder B, and the second storage path is target folder-folder C-folder D. After the storage path of the first file object in the MTP management information is changed according to the first storage path and the second storage path, the MTP management information is shown in Table 5:

[0144] Thereby, the storage path of the first file object is updated in the MTP management information.
[0145] S403: Send a file move response, where the file move response is used to indicate that the first file object has been moved from the source folder to the target folder.
[0146] Figure 4 In the embodiment shown, the storage path of the first file object in the electronic device is first updated from the first storage path to the second storage path based on the renaming function, thereby completing the update of the file management system in the electronic device, based on which, the storage path of the first file object in the MTP management information is changed from the first storage path to the second storage path according to the first storage path, the update of the MTP management information is completed and a file move response is sent to the upper computer, thereby completing the movement of the first file object, and moving the first file object from the source folder to the target folder. The method realizes the movement of the first file object by changing the storage path of the first file object, and does not need to perform operations such as reading, writing, and deleting on the first file object, thereby improving the efficiency of moving the first file object. Secondly, when the movement of the first file object is realized by changing the storage path of the first file object, the file size of the first file object will not have any effect on the movement, so the method will not limit the file size of the first file object, thereby making the flexibility of moving the first file object higher.
[0147] Based on the above embodiments, Figure 5 The file management method provided in the embodiment of the present application is further explained.

For example, for a first file object, the file management interface can include the first file object and can also include a source folder. The first file object in the file management interface is located in the source folder.
[0151] S502: In response to a move instruction for moving a first file object from a source folder to a target folder, determine a second storage path of the file object in the target folder in the electronic device.
[0152] The move instruction may be generated by operating in the file management interface. For example, when a first file object is selected in the file management interface and the first file object is dragged from a source folder to a target folder, a move instruction is generated.
[0153] The host computer determines a second storage path of the file object in the target folder in the electronic device in response to the move instruction.
[0154] S503: Send a file move command based on the first file object and the second storage path, where the file move command is used to instruct to move the first file object from the source folder to the target folder.
[0155] The file move command includes identification information of the first file object and path identification information of the target folder. The identification information of the first file object is used to identify the first file object, and the first file object is used to determine the first storage path of the file object in the source folder in the electronic device; the path identification information of the target folder is used to identify the second storage path, and the first storage path and the second storage path are used to move the first file object from the source folder to the target folder.
[0156] The host computer determines the second storage path of the file object in the target folder in the electronic device based on the move instruction, and determines the identification information of the first file object and the path identification information of the target folder based on the first file object and the second storage path, and generates a file move command according to the MTP protocol, and finally sends the file move command to the electronic device.
[0157] S504: Receive a file move response, where the file move response is used to indicate that the first file object has been moved from the source folder to the target folder.
[0158] After receiving the file move response sent by the electronic device, the host computer can determine that the electronic device has moved the first file object to the target folder. Then, based on the file move response, the host computer updates the file management interface, and the updated file management interface includes the first file object, and the first file object is located in the target folder.
[0159] exist Figure 5 In the illustrated embodiment, when the first file object needs to be moved, operations can be performed in the file management interface to generate a move instruction. Based on the move instruction, the host computer generates a file move command according to the MTP protocol, and sends the file move command to the electronic device. After the electronic device completes the move of the first file object, it receives a file move response sent by the electronic device, and updates the file management interface based on the file move response, so that the first file object in the updated file management interface is located in the target folder. In this method, the host computer generates a file move command and sends the file move command to the electronic device. After receiving the file move response sent by the electronic device, the file management interface is updated, thereby completing the move of the first file object and improving the efficiency of moving the first file object.
