As shown in fig. 2, in one embodiment, there is provided a file processing method including the steps of:
The mobile terminal can monitor the deletion operation of each application program, wherein the deletion operation refers to the operation of deleting the stored files. The application program monitored by the mobile terminal may include a system application and a third party application, where the system application generally refers to an application developed by a manufacturer of the mobile terminal, the mobile terminal may be provided with the system application when the mobile terminal leaves a factory, the third party application generally refers to an application developed by an organization or a person other than the manufacturer, and the third party application may be installed on the mobile terminal when the user uses the mobile terminal.
When an application needs to delete a file, a delete function may be invoked. The mobile terminal can monitor the call of the deletion function, and when the deletion function is detected to be called, the application program calling the deletion function can execute the deletion operation. The mobile terminal can obtain an application program calling a deletion function and obtain a target file of deletion operation, wherein the target file refers to a deleted file. The target files for the deletion operation performed by the application program may be one or more, and may be target files in the same file format or target files in different file formats.
The mobile terminal can obtain the folder to which each target file belongs, and obtain the directory information according to the folder to which the target file belongs, and the file directory can establish the corresponding relation between the file name and the physical address in the storage space. The directory information of the target file may include a folder name to which the target file belongs, a folder storage address to which the target file belongs, and the like. The file directory included in the directory information may be a primary directory, a secondary directory, a multi-level directory, or the like.
The mobile terminal can detect whether the directory information contains a specific flag bit, wherein the specific flag bit can be equivalent to an anti-deletion-error flag bit, and the specific flag bit can be used for indicating that the file in the file directory is a protected and important file. The specific flag bit can be expressed in different modes according to actual requirements.
In one embodiment, the mobile terminal may add a specific flag bit in a file directory through a configuration file, and the configuration file may record configuration information such as a protected file format, a file type, or a file directory. The file format may include, but is not limited to, jpg, doc, gif, etc., and may be represented by a suffix name of the file. The file types may include, but are not limited to, pictures, video, audio, and the like. The mobile terminal can obtain the configuration file, search the file directory corresponding to the configuration information according to the configuration information recorded in the configuration file, and add a specific marker bit in the searched file directory. For example, a protected file type is recorded in the configuration file, and the mobile terminal may find a file directory containing the protected file type and add a specific flag bit in the file directory containing the protected file type.
If the directory information does not include a specific flag bit, it can be indicated that the target file is not a protected file, and the mobile terminal can directly delete the target file. If the directory information contains a specific flag bit, the mobile terminal can determine whether the file format of the target file is a preset format, and the preset format can refer to a protected file format. The mobile terminal can read the file name of the target file and judge whether the file format of the target file is a preset format or not according to the suffix name contained in the file name. Whether the directory information contains the specific zone bit is judged first, and whether the file format of the target file is the preset format is judged after the specific zone bit is contained, so that whether the target file is the protected file can be determined, the detection is carried out from big to small.
And step 240, prompting the deletion operation.
If the file format of the target file is not the preset format, the mobile terminal can directly delete the target file. If the file format of the target file is the preset format, the mobile terminal can prompt the deletion operation. The prompting mode can be set according to actual requirements, for example, prompting information can be displayed on an interface, vibration can be carried out, or voice information can be played for prompting and the like. The mobile terminal can prompt the application program, the target file and the like which are subjected to the deleting operation. For example, but not limited to, a prompt voice "find X application deletes your video" may be played.
In one embodiment, the mobile terminal prompts the deletion operation, and the user can select the prompt, delete the file or keep the file, etc. The mobile terminal can receive the selection operation aiming at the prompt, if the selection operation selects to delete the file, the mobile terminal can directly delete the target file, and if the selection operation selects to reserve the file, the target file can not be deleted, so that the important file can be prevented from being deleted by mistake.
FIG. 3 is a diagram illustrating an interface for prompting a delete operation in one embodiment. As shown in fig. 3, the mobile terminal detects that the application a performs a deletion operation, and a target file for the deletion operation may include 6 photos. The mobile terminal can obtain the directory information of the 6 photos, and can detect that the directory information contains a specific flag bit, and the file format of the 6 photos is a preset format. The mobile terminal may prompt for the delete operation and may present a prompt 302 "find a application deletes your 6 photos" on the interface.
In this embodiment, when it is detected that the application executes the deletion operation, the target file of the deletion operation is acquired, the directory information of the target file is acquired, when the directory information includes the specific flag bit, whether the file format of the target file is the preset format is determined, and if the file format is the preset format, the deletion operation is prompted, so that the important file can be protected, the situation that the important file is deleted by mistake is prevented, and the risk of data loss is reduced.
As shown in fig. 4, in an embodiment, after acquiring the target file of the deletion operation when detecting that the application performs the deletion operation in step 210, the method further includes the following steps:
The mobile terminal detects that the application program executes the deleting operation, can acquire the target file of the deleting operation, and transfers the target file to a temporary directory created in advance. The temporary directory is equivalent to a temporary folder and can be used for caching the target file of the deletion operation. The mobile terminal can set access authority to the temporary directory, and only the application program with the access authority can access the temporary directory. Optionally, the mobile terminal may set the access right of the application program to the temporary directory according to actual requirements, for example, it may be set that the system application has the access right, and the third-party application does not have the access right. The mobile terminal may also count the trust value of each application, which may be determined by a number of different factors, such as the access frequency of the user, the service logic of the application, the update frequency, etc. The application program with the trust value greater than the threshold may be set to have access right, and the application with the trust value less than or equal to the threshold may not have access right.
The mobile terminal transfers the target file to the temporary directory, and may record directory information of the target file before transfer, where the directory information of the target file before transfer may refer to directory information corresponding to a folder to which the target file belongs before transfer.
The mobile terminal can record the time length of the target file transferred to the temporary directory, and when the time length of the target file transferred to the temporary directory reaches a time length threshold value, the target file can be processed, including the processes of deleting the target file or detecting whether the target file is a protected file or not. Alternatively, the time threshold may be set according to actual requirements, such as 5 minutes, 10 minutes, and the like. The mobile terminal may also set a processing time for processing the target files in the temporary directory, for example, when the mobile terminal is in a charging state, the mobile terminal may set a batch processing for each target file included in the temporary directory, and when the mobile terminal is in a screen-off state, the mobile terminal may set a batch processing for the target files included in the temporary directory, but the present invention is not limited thereto. The processing efficiency of the target file can be improved and the power consumption can be reduced.
In one embodiment, when the duration of transferring the target file to the temporary directory reaches the duration threshold, the mobile terminal may obtain directory information of the target file before transferring, and when the directory information includes a specific flag bit, may determine whether the file format of the target file is a preset format. If the file format of the target file is the preset format, the mobile terminal can prompt the deletion operation. The user may select for the prompt. The mobile terminal may receive a selection operation performed for the prompt, and if the selection operation selects a first option, which may be an option to delete a file, the mobile terminal may delete the target file in the temporary directory. If the selection operation selects the second option, which may be a file retention option, the mobile terminal may restore the target file to the directory corresponding to the directory information before the transfer, and restore the target file.
Fig. 5 is a schematic interface diagram for prompting a deletion operation in another embodiment. As shown in fig. 5, the mobile terminal detects that the application a performs a deletion operation, and the target file for the deletion operation may include 6 photos. The mobile terminal can transfer the 6 photos to the temporary directory, when the time length for transferring the 6 photos to the temporary directory reaches the time length threshold value for 3 minutes, the mobile terminal can obtain the directory information of the 6 photos, and can detect that the directory information contains a specific mark bit, and the file format of the 6 photos is a preset format. The mobile terminal may prompt for the deletion operation, and may present a prompt message 502 "find that the a application deleted your 6 photos and needs help you recover? ". The user may select for the reminder 502. When the selection operation received by the mobile terminal is the first option 504, the 6 photos under the temporary directory may be deleted. When the selection operation received by the mobile terminal is the second option 506, the 6 photos may be restored to the directory corresponding to the directory information before the transfer.
In this embodiment, the target file of the deletion operation may be cached through the temporary directory, and when the time length for transferring the target file to the temporary directory reaches the time length threshold, the target file is processed, so that a situation that an important file is deleted by mistake can be further prevented, and a risk of data loss is reduced.
As shown in fig. 6, in an embodiment, after acquiring the target file of the deletion operation when detecting that the application performs the deletion operation in step 210, the method further includes the following steps:
When the application program creates the file, the application identifier may be added to the created file, and the application identifier may be information that can uniquely identify the application program, such as the name and the number of the application program. The application identifier may also be an application summary, the mobile terminal may obtain application information of the application program, the application information may include, but is not limited to, a name, a version number, a developer, an application type, and the like, and the application summary may be generated according to the application information and used as the application identifier. Alternatively, the application Digest may be a Message Digest Algorithm fifth edition (MD 5) Digest, or may be another Algorithm Digest, which is not limited to this.
And step 604, deleting the target file when the application identification of the application program is consistent with the created application identification.
The mobile terminal can obtain the application identifier of the application program for deleting operation, and extract the created application identifier of each target file for deleting operation, wherein the created application identifier is the application identifier of the application program for creating the target file. The mobile terminal can compare the application identifier of the application program subjected to the deleting operation with the created application identifier and judge whether the application identifier and the created application identifier are consistent. If the application identifier of the application program subjected to the deletion operation is consistent with the created application identifier, it can be shown that the application programs for creating and deleting the target file are the same, and the mobile terminal can directly delete the target file.
If the application identifier of the application program performing the deletion operation is not consistent with the created application identifier, it may be stated that the application programs creating and deleting the target file are different. The mobile terminal can detect whether the target file is a protected file or not, can judge whether the directory information of the target file contains a specific flag bit or not, and if so, further judges whether the file format of the target file is a preset format or not. If the target file is a protected file, the mobile terminal can prompt the deletion operation.
In this embodiment, when the application programs for creating the target file and deleting the target file are consistent, the target file is directly deleted without detecting whether the target file is a protected file, so that the detection times are reduced, the detection efficiency can be improved, and the system power consumption can be reduced.
In one embodiment, after acquiring the target file of the deletion operation when the application program is detected to perform the deletion operation in step 210, the method further includes: when the application program exists in the white list, the target file is deleted.
The mobile terminal may store a white list in which trusted applications may be recorded. When the mobile terminal detects that the application program is executing the deleting operation, the application identifier of the application program can be obtained, and whether the application program exists in the white list or not is judged according to the application identifier. If the application program exists in the white list, the mobile terminal can directly delete the target file without detecting whether the target file is a protected file.
In one embodiment, the whitelist may include a local whitelist and a cloud whitelist, in which trusted system applications and third party applications may be recorded. The mobile terminal developer can research and test each application program in the market and calculate the trust value of each application program, wherein the trust value can be calculated according to the service logic, the updating frequency, the downloading user amount and the like of the application program. A developer of the mobile terminal can update the cloud white list at regular time according to the research and test results, trusted application programs are added into the cloud white list, the application programs with the trust values larger than the trust threshold value can be added into the white list, the flexibility of the white list is improved, and the application programs of the white list are enabled to be in line with the market.
Before judging whether the application program subjected to the deleting operation exists in the white list, the mobile terminal can obtain the local white list and the cloud white list, compare the local white list with the cloud white list and judge whether the local white list and the cloud white list are consistent. And if the application program in the local white list is inconsistent with the application program in the cloud white list, updating the local white list according to the cloud white list with reference to the cloud white list, and ensuring the synchronization between the local white list and the cloud white list. Optionally, the mobile terminal may also obtain the local white list and the cloud white list at a fixed time, and perform synchronization between the two, for example, the mobile terminal may perform synchronization at 4 am, or perform synchronization when the mobile terminal is powered on, but is not limited thereto.
In this embodiment, when the application program performing the deletion operation exists in the white list, the target file may be directly deleted without detecting whether the target file is a protected file, so as to reduce the number of detection times, improve the detection efficiency, and reduce the power consumption of the system.

When the mobile terminal is started, the protected file directory can be configured, and a specific zone bit is added in the protected file directory. When the mobile terminal is started, the mobile terminal can obtain a configuration file, and the configuration file can record configuration information such as protected file formats, file types or file directories. Optionally, the configuration file may include a local configuration file and/or a cloud configuration file, the local configuration file is stored locally in the mobile terminal, and the cloud configuration file may be stored in the server. The mobile terminal can acquire the cloud configuration file from the server, and update the local configuration file according to the cloud configuration file, so that synchronization between the cloud configuration file and the local configuration file is guaranteed.
After the mobile terminal updates the local configuration file, the directory information added with the specific flag bit can be determined according to the local configuration file. The mobile terminal can search the file directory corresponding to the configuration information according to the configuration information recorded in the local configuration file, write the searched directory information into the kernel file, and add a specific flag bit in the searched directory information. The mobile terminal can write the directory information into the kernel file during the period from the start-up to the interface entry, so that the file detection efficiency can be improved.
When the mobile terminal detects that the application program executes the deleting operation, the directory information of the target file of the deleting operation can be obtained, the kernel file is read, whether the directory information of the target file exists in the kernel file or not is judged, and if the directory information exists in the kernel file, the directory information can be determined to contain the specific zone bit.
