Referring to fig. 2, fig. 2 is a schematic flowchart of a file processing method provided in an embodiment of the present application, and the file processing method is applied to a mobile terminal, and includes:
s201, when detecting a deletion request of a third-party application of the mobile terminal for a target file, the mobile terminal determines the file type of the target file;
the third-party application comprises various applications installed in the using process of the mobile terminal, such as an instant messaging application, a browser application and the like.
The file type of the target file may be, for example, a photo, a system file, an internal storage space file, etc., and may be preset by a user, and the target file may be classified according to a directory of the file to which the target file belongs, or classified according to a function thereof, etc., which is not limited uniquely.
S202, when the mobile terminal detects that the file type is a preset file type, performing behavior validity detection on the deletion request to obtain a detection result;
s203, if the mobile terminal determines that the detection result is legal, deleting the target file, and feeding back a deletion response to the third party application to prompt the third party to continue to execute subsequent operations;
the subsequent operations executed by the third-party application may be various, and specifically, the subsequent operations are related to the function currently running by the third-party application, for example, when the third-party application is executing version update, the version update process needs to execute multi-step operations, where deleting the target file is one of the multi-step operations, and the operation after deleting the target file is the subsequent operation.
S204, if the mobile terminal determines that the detection result is illegal, the target file is transferred to a recycling bin, the deletion response is fed back to the third party application to enable the third party to continue to execute subsequent operations, and the target file is recovered from the recycling bin after the subsequent operations are executed.
It can be seen that, in the embodiment of the present application, when detecting a deletion request of a third-party application of the mobile terminal for a target file, the mobile terminal determines a file type of the target file, and when detecting that the file type is a preset file type, performs behavior validity detection on the deletion request to obtain a detection result, and if determining that the detection result is legal, deletes the target file, and feeds back a deletion response to the third-party application to prompt the third party to continue to execute subsequent operations, and if determining that the detection result is illegal, transfers the target file to a recycle bin, and feeds back the deletion response to the third-party application to prompt the third party to continue to execute the subsequent operations, and recovers the target file from the recycle bin after the subsequent operations are completed. The method has the advantages that the mobile terminal can detect the legality of the file of the deletion request at this time by the home terminal according to the file deletion request of the third-party application, delete the target file under the legal condition and feed back the deletion response to ensure the normal operation of the third-party application, timely transfer the target file under the illegal condition to avoid the mistaken deletion of the target file, feed back the deletion response to ensure the normal operation of the third-party application, and reply the target file after the subsequent operation of the third-party application is completed, so that the target file cannot be timely searched due to position transfer is avoided, the safety and intelligence of file protection of the mobile terminal are improved, and the operation stability of the application is effectively ensured.
In one possible example, the performing, by the mobile terminal, the validity detection on the deletion request to obtain a detection result includes: the mobile terminal acquires a preset condition set, wherein the condition set comprises a plurality of conditions for judging the validity of a deleting action; executing preset operation aiming at each condition to obtain a condition detection result, wherein the preset operation comprises the steps of obtaining state information required by each condition and determining the condition detection result according to the state information; and determining the detection result of the deletion request according to the number of legal detection results in the condition detection result.
It can be seen that, in this example, since the deletion request of the third-party application for the target file needs to be analyzed in combination with the characteristics of the situation of illegally deleting the file when the user does not directly participate in the validity confirmation, generally, when the file is deleted due to a program error or the like in the background of the third-party application, a plurality of consecutive files are deleted, and taking a photo as an example, the photo of this album may be deleted in a short time, so that by multi-dimensional condition detection, it is possible to more accurately locate whether the current deletion request belongs to the illegal deletion request, avoid that the file of the mobile electronic is illegally deleted, and improve the security of file processing performed by the mobile terminal.
In one possible example, the plurality of conditions for determining the validity of the deletion behavior includes at least two of: the method comprises the steps of obtaining a target file, wherein the target file comprises a condition of quantity dimension of the target file, a condition of file continuity dimension of the target file, a condition of proportion dimension of the target file in a file directory and a condition of using heat dimension of the target file, and the file directory is a directory to which the target file belongs.
The condition of the number dimension of the target files may be, for example, that when the third-party application background requests to delete a target file, if the number of the target files requested to be deleted is greater than or equal to a preset number, the corresponding condition detection result is illegal, and if the number is less than the preset number, the corresponding condition detection result is legal.
The condition of the file continuity dimension of the target file may be, for example, that when the third-party application background requests to delete the target file, if the file continuity of the target file requested to be deleted is adjacent to each other, the corresponding condition detection result is illegal, and if the file continuity of the target file requested to be deleted is at random intervals, the corresponding condition detection result is legal.
The condition of the proportion dimension of the target file in the file directory may be, for example, that when the third-party application background requests to delete the target file, if the quantity proportion of the target file in the file directory is less than or equal to the preset proportion, the corresponding condition detection result is illegal, and if the quantity proportion of the target file in the file directory is greater than the preset proportion, the corresponding condition detection result is legal.
The condition of the usage heat dimension of the target file may be, for example, that when the third-party application background requests to delete the target file, if the usage heat of the target file is greater than or equal to the preset heat, the corresponding condition detection result is illegal, and if the usage heat of the target file is less than the preset heat, the corresponding condition detection result is legal.
Therefore, in this example, the mobile terminal can obtain an accurate detection result as much as possible in the number dimension, the file continuity temperature, the file proportion dimension, and the usage heat dimension, and the accuracy of detecting the file deletion validity is improved.
In one possible example, the performing, by the mobile terminal, the validity detection on the deletion request to obtain a detection result includes: the mobile terminal determines the file type of the target file; screening out files which accord with the deletion habit of the user from the target files through the file screening model; calculating the proportion of the file which accords with the deletion habit of the user relative to the target file; and determining the detection result of the deletion request according to the ratio.
It can be seen that in this example, since the deletion habit of the user is generally continuous and unchanged for the same type of file, for example, for a photo, the user may be used to delete an overexposed photo, a half-length photo, and the like, the files meeting the deletion habit of the user in the target file are predicted through the file screening model meeting the user habit, the occupation ratio is further calculated, the detection result is accurately identified according to the occupation ratio, the misrecognition rate is reduced, and the accuracy of detecting the validity of file deletion is improved.
In one possible example, the method further comprises: the mobile terminal acquires a file record of a user actively deleting a file; screening out file records of which the file types of the deleted files are the same as the file types of the target files from the file records; and training a preset model according to the screened file records to obtain the file screening model.
Therefore, in this example, the mobile terminal can obtain the file screening model with higher prediction accuracy through model training, so that the accuracy of file screening is improved.

s303, the mobile terminal executes preset operation aiming at each condition to obtain a condition detection result, wherein the preset operation comprises the steps of obtaining state information required by each condition and determining the condition detection result according to the state information;
s304, the mobile terminal determines the detection result of the deletion request according to the number of legal detection results in the condition detection result.
S305, if the mobile terminal determines that the detection result is legal, deleting the target file, and feeding a deletion response back to the third-party application to prompt the third party to continue to execute subsequent operations;
s306, if the mobile terminal determines that the detection result is illegal, the target file is transferred to a recycling bin, the deletion response is fed back to the third-party application to prompt the third party to continue to execute subsequent operations, and the target file is recovered from the recycling bin after the subsequent operations are executed.

The method has the advantages that the mobile terminal can detect the legality of the file of the deletion request at this time by the home terminal according to the file deletion request of the third-party application, delete the target file under the legal condition and feed back the deletion response to ensure the normal operation of the third-party application, timely transfer the target file under the illegal condition to avoid the mistaken deletion of the target file, feed back the deletion response to ensure the normal operation of the third-party application, and reply the target file after the subsequent operation of the third-party application is completed, so that the target file cannot be timely searched due to position transfer is avoided, the safety and intelligence of file protection of the mobile terminal are improved, and the operation stability of the application is effectively ensured.
In addition, since the third-party application needs to analyze the characteristics of the situation of illegally deleting the file when the user does not directly participate in the validity confirmation for the deletion request of the target file, generally, when the third-party application background deletes the file due to a program error or the like, a plurality of continuous files are deleted, and the photo of the album may be deleted in a short time by taking the photo as an example, so that whether the current deletion request belongs to the illegal deletion request can be more accurately located through multi-dimensional condition detection, the file of the mobile electronic is prevented from being illegally deleted, and the security of file processing by the mobile terminal is improved.
