Description

Technical Field

[0001] This application relates to the field of document management, and more particularly to a document management method, apparatus, and computer program product. Background Technology

[0002] Currently, most network file sharing solutions fall into several categories. One is the client-server (C / S) architecture with a central server, such as Server Messages Block (Samba), File Transfer Protocol (FTP), and cloud storage services. In this architecture, the server shares its stored content with various clients according to a specific protocol, and the clients read and manipulate files on the server according to the same protocol. Another type is a distributed file management system, which stores files across multiple computers or storage nodes and provides a unified file access interface. These existing technologies cannot meet the needs of network penetration and distributed storage management for edge-side Internet of Things (IoT) devices, nor are they sufficient to solve the problem of data privacy. Summary of the Invention

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0034] The following is in conjunction with the appendix Figures 1 to 7 This application provides a detailed description of a file management method, apparatus, and computer program product through specific embodiments and application scenarios. This embodiment offers a file management method based on Network Address Translation (NAT), which overcomes the limitations of local area networks and allows for access anytime, anywhere via the external network, freeing users from the constraints of centralized storage servers and protecting user private data and privacy. The file management apparatus of this application is compact and flexible, requiring minimal space and resources, making it easy to deploy on edge IoT devices.

[0035] like Figure 1 The diagram shown is a flowchart of a file management method provided in an embodiment of this application. Figure 1 As shown, the file management method is applied to the control terminal, and the file management method may include the contents shown in S101 to S103.

[0036] In S101, upon receiving a user's access request, a file management command is generated based on the access request.

[0037] In S102, a file management command is sent to the device side so that the device side can perform file transfer based on the file management command.

[0038] It's worth noting that peer-to-peer (P2P) networking or other network traversal technologies can be used to interconnect and connect multiple devices. By establishing point-to-point connections, multiple devices can communicate directly without the involvement of a central server, creating a virtual file system underlying the network across different network environments. A virtual file system is deployed on each device, which virtually combines the file systems and directory structures of multiple devices into a single, unified file system. Based on user requests, file operations are transmitted to the appropriate device using network traversal technology, and the results are returned to the user.

[0039] In S103, the operation result returned by the receiving device is received.

[0040] In this embodiment, upon receiving a user's access request, the control terminal first generates a file management command based on the request, then sends the file management command to the device side, enabling the device side to perform file transfer based on the command. Finally, the control terminal receives the operation result returned by the device side. This embodiment, by implementing network traversal and virtual file management, can meet users' needs for cross-device file access and operation.

[0041] like Figure 2 and 3 The diagram shown illustrates the underlying network penetration and network interconnection.

[0042] in, Figure 2 It is a star topology, meaning that the mobile device (i.e., the first device) and the IoT device (i.e., the second device) are connected separately, and there is no connection between the IoT devices. Figure 3 It is a symmetrical mode, meaning that mobile devices and IoT devices are connected, and IoT devices are also interconnected.

[0043] In one possible implementation of this application, before generating a file management command based on the access request upon receiving a user's access request, the file management method may further include: establishing a connection between a first device corresponding to the control terminal and multiple second devices corresponding to the device side; through the connection, the first device communicates directly with the multiple second devices.

[0044] The connection in this embodiment can include two types: one is a star topology, such as... Figure 2 As shown; one is a symmetrical pattern, such as Figure 3 As shown.

[0045] In other words, the first step is to achieve network traversal and interconnection. Specifically, existing P2P technology or other network traversal technologies can be used to enable interconnection and connection between multiple devices. By establishing point-to-point connections, multiple devices can communicate directly without the involvement of a central server. This allows the creation of a virtual file system underlying network in different network environments.

[0046] A virtual file system is deployed on each device, which can virtualize the file systems and directory structures of multiple devices into a single, unified file system. The first device controlling the terminal (e.g., ...) Figure 2 and Figure 3 A virtual file system server is deployed on mobile devices (such as mobile devices in the device), and various second devices on the device side (such as mobile devices in the device) Figure 2 and Figure 3A virtual file system client is deployed on IoT devices 1, 2, 3, etc. The virtual file system server can, based on user requests at the application layer, pass file operations to the corresponding second devices using network traversal technology and return the results to the user. In this way, users can access and manipulate files on multiple devices (i.e., second devices) from the external network using the file system and directory structure of one device (i.e., the first device).

[0047] In one possible implementation of this application, establishing a connection between the first device corresponding to the control terminal and a plurality of second devices corresponding to the device side may include: establishing a connection between the first device corresponding to the control terminal and a plurality of second devices corresponding to the device side respectively, wherein the connection relationship between the plurality of second devices includes mutual connection and non-connection.

[0048] In other words, the connection mode between devices can be either a star topology or a symmetric topology. This frees users from the constraints of centralized storage servers and protects their private data and privacy.

[0049] In one possible implementation of this application, file management commands may include at least one of file moving, file copying, and file deletion.

[0050] like Figure 4 The diagram shown is a flowchart of a file management method provided in an embodiment of this application. Figure 4 As shown, the file management method is applied to the device side, and the file management method may include the contents shown in S401 to S403.

[0051] In S401, file management commands sent by the control terminal are received.

[0052] In S402, file management commands are distributed to multiple second devices so that the multiple second devices can execute the file management commands.

[0053] In S403, the operation result is sent to the control terminal.

[0054] In this embodiment, a file management command is first received from a control terminal. Then, the file management command is distributed to multiple second devices, enabling the second devices to execute the file management command. Finally, the operation result is sent back to the control terminal. This embodiment allows the control terminal to manage file transfers across multiple second devices, satisfying users' needs for cross-device file access and operation.

[0055] In one possible implementation of this application, multiple second devices are interconnected, and the execution of file management commands by the multiple second devices may include: file transfer between the various second devices based on the file management commands, and the file transfer includes at least one of file moving, file copying, and deletion.

[0056] In one possible implementation of this application, the multiple second devices are not connected to each other. The execution of file management commands by the multiple second devices may include: based on the file management commands, the second devices transfer files through the first device corresponding to the control terminal. The file transfer includes at least one of file moving and file copying.

[0057] The following is an example using a single mobile device (e.g., a smartphone) and multiple IoT devices (e.g., device 1, device 2, device 3):

[0058] The mobile device creates a service instance server in the virtual file system;

[0059] 1) Create a service instance client in each of Device 1, Device 2, and Device 3;

[0060] 2) The server service instance is responsible for requesting the file list from each device client, and then organizing, combining, sorting, paginating, etc. according to the database logic, and providing it to the application layer for invocation;

[0061] 3) The server service instance receives access from the application layer, distributes commands for different operations, and coordinates various device clients to perform operations such as reading files, transferring files, and modifying files;

[0062] 4) The client service instance is responsible for reading and manipulating the physical file systems of device 1, device 2, and device 3;

[0063] 5) The client service instance is responsible for receiving commands from the server and transferring files between devices;

[0064] 6) Copying and moving operations between Device 1, Device 2, and Device 3. For a star topology, this operation can be forwarded through the mobile device server. For example, if Device 1 copies a file to Device 2, Device 1's client first divides the file into chunks, uploads the chunks to the mobile device server, and then the server forwards them to Device 2's client. For a symmetric topology, the command is issued by the mobile device server, and the data does not need to be forwarded; it is directly transmitted between the two IoT devices. For example, if Device 1 copies a file to Device 2, Device 1's client receives the instruction from the mobile device server and directly sends the file to Device 2's client.

[0065] In higher-level applications, users can access and manipulate files through the interfaces provided by the virtual file system. Users can read, write, copy, and move files in the virtual file system just like they would local files. The virtual file system forwards these operations to the appropriate devices and returns the results to the user.

[0066] On mobile devices, you can display all files and folders of Device 1, Device 2, and Device 3; select multiple files to copy and move to a folder of Device 1, Device 2, and Device 3; modify and delete files and folders of Device 1, Device 2, and Device 3; and copy, move, or delete files and folders between Device 1, Device 2, and Device 3.

[0067] This application's embodiment is based on a decentralized solution using network penetration. Its software design logic is simple, it consumes few resources, and it is suitable for file storage management on edge IoT devices. It has horizontal scalability, allowing for the dynamic addition of more IoT devices to meet greater storage needs. This embodiment can be applied in smart homes, the Internet of Things, and other fields, enabling data sharing and interoperability between devices.

[0070] In this embodiment, upon receiving a user's access request, the generation module 501 first generates a file management command based on the access request. Then, the first sending module 502 sends the file management command to the device side, enabling the device side to perform file transfer based on the file management command. Finally, the first receiving module 503 receives the operation result returned by the device side. This embodiment, by implementing network traversal and virtual file management, can meet users' needs for cross-device file access and operation.

Finally, the operation result is sent back to the control terminal. This embodiment allows the control terminal to manage file transfers across multiple second devices, satisfying users' needs for cross-device file access and operation.
