A system service may be initiated for handling deletion events, through which file deletion operations are detected. The file deletion operation may be initiated by a user actively or by an application program.
Before detecting the file deletion operation, the method may further include:
and opening a file deletion record switch.
When the file deleting record switch is turned on, the file attribute and the corresponding operation attribute are recorded while the media file is deleted when the file deleting operation of the media file is detected, the file deleting record switch is turned on by default, and a user can turn on or turn off the file deleting record switch, so that the man-machine interaction is improved. If the file deletion record switch is not turned on, the deletion can be performed in a normal manner, i.e. the file attribute and the operation attribute are not recorded.
And step 120, when the operation object of the file deleting operation is a media file, deleting the media file.
The media files comprise picture files, audio files or video files and the like.
When the file deleting operation is detected, a system service interface can be called through a system layer deleting interface to judge whether an operation object of the file deleting operation is a media file such as a picture or audio and video. Specifically, in the determination, a suffix name of the operation object may be acquired, and whether the operation object is a media file such as a picture file, an audio file, or a video file is determined according to the suffix name, the operation object is determined to be a video file if the suffix name is rmvb, avi, or the like, the operation object is determined to be an audio file if the suffix name is MP3, wav, or the like, and the operation object is determined to be a picture file if the suffix name is a common picture format suffix such as jpg, png, or the like.

The identifier of the mobile terminal may be an International Mobile Equipment Identity (IMEI) of the mobile terminal, or may be a Media Access Control (MAC) address of the mobile terminal. The IMEI is used to identify each individual Mobile phone in a GSM (global system for Mobile Communication) Mobile network, and corresponds to an identification number of the Mobile phone. The MAC address is used to represent an identifier of each station on the internet, expressed as a hexadecimal number, for a total of six bytes (48 bits).
According to the technical scheme of the embodiment, on the basis of the embodiment, the file attribute and the operation attribute in the database are synchronized to the server regularly, and the file attribute and the operation attribute in the database are deleted, so that the file attribute and the corresponding operation attribute can be stored for a long time, the storage space of the mobile terminal is saved, and a user can search the record of the loss of the media file through a background and locate the loss reason.
EXAMPLE III
Fig. 3 is a flowchart of a method for deleting a media file according to a third embodiment of the present invention, which is optimized based on the third embodiment, and further optimizes "when an operation object of the file deletion operation is a media file, the media file is deleted" to "when the operation object of the file deletion operation is a media file, prompt a user; and deleting the media file when a confirmation operation of the user is received. The method specifically comprises the following steps:
And step 320, when the operation object of the file deleting operation is the media file, prompting a user.
When the suffix name of the operation object of the file deletion operation is judged, and the operation object is judged to be the media file, the prompt can be provided for the user in a pop-up prompt box mode, for example, the user can be prompted to 'delete the media file, and once the deletion is not recoverable'. The media files can be replaced by specific file formats, namely when the operation is judged to be the picture files through the suffix name, the user can be directly prompted to delete the picture files and cannot be recovered once the picture files are deleted; when the operation object is judged to be the audio file through the suffix name, the user can be directly prompted to delete the audio file and cannot be recovered once the audio file is deleted; when the operation object is judged to be a video file through the suffix name, the user can be directly prompted to delete the video file, and the video file cannot be recovered once deleted.
And step 330, deleting the media file when the confirmation operation of the user is received.
And after the user clicks the confirmation button in the prompt box, the mobile terminal receives the confirmation operation of the user, and deletes the media file after receiving the confirmation operation of the user. And if the cancel operation of the user is received, the media file is not deleted any more.
In this embodiment, the operation attribute may further record whether the user agrees to the operation.
According to the technical scheme of the embodiment, when the operation object of the file deletion operation is the media file, the user is prompted, and the media file is deleted only when the confirmation operation of the user is received, so that the user or an application program is prevented from deleting the important media file of the user, and the media file can be prevented from being deleted by mistake.
Example four
Fig. 4 is a flowchart of a method for deleting a media file according to a fourth embodiment of the present invention, where this embodiment is optimized based on the foregoing embodiment, and after the file attribute and the operation attribute are stored in the database, the method further includes: according to the deletion source in the operation attribute, counting the number of file deletion operations which belong to the same deletion source and are stored in a database at intervals of preset time; and when the number is larger than a preset value and the deletion source is an application program, prompting a user that the application program deletes the media files frequently. The method specifically comprises the following steps:
In step 420, when the operation object of the file deletion operation is a media file, deleting the media file.
Because the deletion source is the initiator of the file deletion operation, the deletion source initiating more file deletion operations is determined by counting the number of file deletion operations initiated by the same deletion source. In the counting, the counting may be performed once per a preset time, for example, once per month.
And step 450, when the number is larger than the preset value and the deletion source is the application program, prompting the user that the application program deletes the media files frequently.
Because the user is the user of the mobile terminal, the user may also initiate more file deletion operations, the subjective deletion behavior of the user does not need to prompt the user, but only judges that the deletion source is the deletion behavior of the application program, and when the number of file deletion operations of the same deletion source is greater than a preset value (for example, 5 times) and the deletion source is the application program, the user is prompted to delete the media files more frequently by the application program, and the user processes the application program.
In the technical solution of this embodiment, on the basis of the above embodiment, the number of file deletion operations belonging to the same deletion source stored in the database is periodically counted, and when the number is greater than the preset value and the deletion source is an application program, the user is prompted that the application program frequently deletes media files, so that the user can process the rogue application program.
