When a user performs a corresponding operation on a computer to implement a file management operation for deleting a file in a mobile phone, the file in the mobile phone is easily lost due to a misoperation in the file management operation.
In the embodiment of the application, after receiving file operation request information which is sent by an external terminal and carries a deletion operation code and file identification information of a first target file, file data of the first target file is obtained according to the file identification information of the first target file, a second target file is created on a preset storage path, the file data is written into the second target file, and then the first target file is deleted.
Fig. 1 shows a schematic flow chart of a file management method implemented by a terminal device, which can be executed by a file management apparatus configured on the terminal device, and is suitable for avoiding a situation where a file in the terminal device is lost due to an operation error or other reasons in a file management operation, including steps 101 to 104.
The terminal equipment comprises terminal equipment provided with a file management device, such as a smart phone, a tablet personal computer, a learning machine, a digital camera, a walkman and the like.
The external terminal may be a computer, a server, or other terminal equipment.
In this embodiment of the application, the receiving of the file operation request information sent by the external terminal means that after the terminal device establishes a connection with the external terminal, the terminal device receives the file operation request information sent by the external terminal, so as to implement file management operations, such as copying, pasting, cutting, deleting, and the like, performed on a file in the terminal device by the external terminal.
The operation code carried by the file operation request information is used to determine the specific operations that the file operation request information needs to be executed by the terminal device, such as file management operations of copying, pasting, cutting, deleting, and the like. The file identification information of the first target file carried in the file operation request information is used to determine a target object of a specific operation executed by the end device, that is, an object for which the external terminal device needs to execute the file management operation on the terminal device.
And 102, if the operation code is a delete operation code, acquiring file data of the first target file according to the file identification information of the first target file.
The deleting operation code is used for instructing the terminal equipment to store the first target file in a preset storage path and delete the first target file from an original storage path.
The file data includes file attribute data and file content data, wherein the file attribute data includes attribute data such as an original storage path, a file size, a file name, a storage format of the file, and the file content data refers to the content of the file itself.
In this embodiment of the application, when it is determined that an operation code in file operation request information sent by a received external terminal is a delete operation code, file data of the first target file is obtained according to file identification information of the first target file, so that the first target file is stored in a preset storage path.
Optionally, in some embodiments of the present application, before receiving the file operation request information sent by the external terminal, the method includes: and when connection is established with an external terminal, sending an operation code set to the external terminal, wherein the operation codes in the operation code set comprise the deletion operation codes.
Since the operation codes that can be supported by different terminal devices are different, when the terminal device establishes a connection with the external terminal, the terminal device needs to send an operation code set of the terminal device to the external terminal, so that the external terminal device can pre-load a call function corresponding to the operation code that can be supported by the terminal device. The operation codes in the operation code set comprise the deletion operation codes, so that the external terminal can send file operation request information carrying the deletion operation codes to the terminal equipment.
It should be noted that the establishing of the connection between the terminal device and the external terminal includes establishing a connection based on an MTP transport protocol.
In this embodiment of the application, after the file data is acquired, a second target file is created on a preset storage path, and the file data is written into the second target file, so that the second target file is the same except for the storage path of the first target file.
The preset storage path may be a fixed storage path which is divided in advance, or a storage path corresponding to a storage space which is divided according to the use condition of the storage space of the terminal device after receiving the file operation request information carrying the delete operation code.
And 104, deleting the first target file.
In this embodiment of the application, after a second target file is created on the preset storage path and the file data of the first target file is written into the second target file, the first target file may be deleted, so as to complete the deletion operation corresponding to the deletion operation code.
Wherein deleting the first target file comprises marking the first target file as a deleted file in a media database of the MTP.
Optionally, after deleting the first target file, the method includes: sending a file updating instruction to the external terminal; the file update instruction is used for instructing the external terminal to update the file information displayed in the external terminal.
When the terminal equipment is connected with the external terminal in an MTP mode, the file related information recorded in the MTP database of the terminal equipment is displayed on the external terminal, at the moment, the file related information recorded in the MTP database is presented on the external terminal instead of each file in the terminal equipment, the external terminal equipment can access the file recorded in the MTP database of the terminal equipment, and if the related information of a certain file in the terminal equipment is not recorded in the MTP database, the external terminal cannot display the file.
Therefore, after the terminal device creates the second object file and deletes the first object file, the MTP database needs to be updated and a file update command is sent to the external terminal, so that the file information displayed in the external terminal can be updated.
Optionally, as an implementation manner of the present application, as shown in fig. 2, in step 103, creating a second target file on a preset storage path, and writing the file data into the second target file, where the method includes: step 201 to step 202.
The preset file type may be a file type divided according to a storage format of the file, for example, the file with the storage format being doc storage format, dox storage format, xlsx storage format, ppt storage format, pdf storage format, or picture format is divided into a preset file type, and the file with the txt storage format and rar storage format is divided into a non-preset file type.
The preset file type may be a file type divided according to a source of the file, for example, the file created on the terminal device and the file received from the instant chat application are divided into preset file types, and the file received from another application is divided into non-preset file types.
In this embodiment, when the file type of the first target file is determined to be the preset file type, a second target file is created on a preset storage path, the file data is written into the second target file, and then the first target file is deleted, so that a user can obtain the file from the preset storage path when needing to restore the first target file, thereby avoiding the file loss in the terminal device due to misoperation or other operations in the file management operation.
Optionally, in this embodiment of the application, when it is determined that the file type of the first target file is a non-preset file type, the first target file is directly deleted, so as to save a storage space of the terminal device.
In the above-described embodiment, as shown in fig. 3, step 103 may further include, before creating a second target file on a preset storage path and writing the file data into the second target file: step 301 to step 302.
Since the capacity of the data that can be stored in the preset storage path is limited, and the file that has been stored in the preset storage path may be data that has not been deleted after a long time of storage, creating a second target file on the preset storage path, and deleting the file stored in the preset storage path according to a preset rule when it is determined that the remaining storage capacity of the preset storage path is smaller than the data amount of the file data before writing the file data into the second target file, so that the file that has been stored in the preset storage path can be automatically updated after the file is full.
For example, the deleting the file stored in the preset storage path according to the preset rule may include: and acquiring the creation time of the files stored in the preset storage path, and deleting the files stored in the preset storage path in sequence according to the sequence of the creation time until the residual storage capacity of the preset storage path is greater than or equal to the data volume of the file data.
For another example, the deleting the file stored in the preset storage path according to the preset rule may include: and deleting the minimum number of files stored in the preset storage path according to the data quantity required by the file data, wherein the time interval between the creation time of the deleted files and the current time is greater than the preset time interval. For example, the preset time interval may be 15 days.
In some embodiments of the present application, as shown in fig. 3, after the determining whether the remaining storage capacity of the preset storage path is smaller than the data amount of the file data, the method may further include: step 303 or step 304.
It should be noted that, in practical applications, the prompt window for popping up whether to completely delete the first object file may be a prompt window for popping up whether to completely delete the first object file on the terminal device, or may be configured to control the external terminal to display the prompt window, and then receive a complete deletion instruction sent by the external terminal to directly delete the first object file, so that file loss caused by the first object file being deleted by mistake is avoided as much as possible by means of user participation.
In the above-described embodiment, as shown in fig. 4, the step 103, creating a second target file on a preset storage path, and after writing the file data into the second target file, may further include: step 401 and/or step 402.
The recovery instruction based on the second target file may be a recovery instruction triggered by the user on the external terminal, and the recovery instruction may carry a recovery operation code and file identification information of the second target file.
The restoring the first object file according to the restoring instruction and the file data written in the second object file may include: acquiring file data of the second target file from the preset storage path according to the file identifier of the second target file to obtain an original file storage path in the file data; and creating a new first target file in the original file storage path, writing the file data of a second target file into the new first target file, and then deleting the second target file in the preset storage path, thereby completing the recovery of the first target file.
In this embodiment, since the second object file is a file stored in the preset storage path, after the second object file is deleted according to the deletion instruction, the second object file can be completely deleted, so that the storage space of the terminal device can be freed and used for storing other second object files that need to be temporarily stored.
