Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a file processing method according to an embodiment of the present disclosure. As shown in fig. 2, the file processing method in the embodiment of the present application includes the following operations:
201, when detecting that a deletion request of a third party application for a plurality of files is an illegal deletion request, dividing the plurality of files into a plurality of file sets by an electronic device, wherein the deletion request is a request of the third party application in a preset operation process.
The third-party application includes various application programs installed in the use process of the electronic device, such as an instant chat application, a video application, a graphical user interface application, and the like, which are not limited herein.

202, the electronic device performs a transfer operation for a file in a first set of files in the plurality of sets of files.
203, the electronic device performs a deletion detection operation on files in the ith file set, and simultaneously performs a transfer operation on files in the (i + 1) th file set, wherein the deletion detection operation is used for detecting whether the files in the ith file set are deleted, the transfer operation is used for transferring the files in the (i + 1) th file set from an original storage space of the electronic device to a preset storage space, the plurality of file sets comprise the ith file set and the (i + 1) th file set, and i is a positive integer which is greater than or equal to 1 and less than or equal to the number of the file sets.
It can be seen that in the file processing method provided in the embodiment of the present application, when detecting that a deletion request of a third party application for multiple files is an illegal deletion request, an electronic device divides the multiple files into multiple file sets, where the deletion request is a request in a process of executing a preset operation by the third party application, executes a transfer operation for a file in a first file set of the multiple file sets, then executes a deletion detection operation for a file in an ith file set, and at the same time, executes a transfer operation for a file in an (i + 1) th file set, where the deletion detection operation is used to detect whether the file in the ith file set is deleted or not, the transfer operation is used to transfer the file in the (i + 1) th file set from an original storage space of the electronic device to a preset storage space, and the multiple file sets include the (i + 1) th file set and an (i + 1) th file set, i is a positive integer greater than or equal to 1 and less than or equal to the number of file sets. Therefore, when detecting that the deletion request of the third-party application for the plurality of files is an illegal deletion request, the electronic device divides the files to be deleted into the plurality of file sets and processes deletion detection operation and transfer operation of the file sets in parallel, so that the real-time property of file processing is improved, data loss caused by mistakenly deleting the files by the third-party application is avoided, and user loss is reduced.
In one embodiment, the electronic device may further perform the following:
generating a deletion response message when detecting that a result of a deletion detection operation for a file in a kth file set is that a file in the kth file set is deleted, wherein the kth file set is a last file set of transfer operations performed by the third-party application for the plurality of file sets;
feeding back the deletion response message to the third-party application to prompt the third-party application to continue to perform subsequent operations.
The subsequent operations executed by the third-party application may be various, and specifically, depending on the function that the current third-party application is running, if the third-party application is executing version update, the version update process needs to execute multiple steps of operations, where deleting the target file is one of the multiple steps of operations, and the operation after deleting the target file is the subsequent operation.
The third-party application can receive the deletion response message in time so as to smoothly execute the subsequent operation, so that the execution flow of the third-party application side is smooth and errorless.
In the prior art, when the electronic device transfers a plurality of files to the preset storage space, all the files are transferred to the preset storage space first, then deletion detection operation is performed, and then a deletion response message is fed back to the third-party application. According to the method and the device, the plurality of files are divided into the plurality of file sets, deletion detection operation of the files in the ith file set and transfer operation of the files in the (i + 1) th file set are processed in parallel, the speed of the third-party application receiving the feedback deletion response message is improved, and then the recovery speed of the deleted files is improved.
Therefore, when the last file set completes the deletion detection operation and the result of the deletion detection operation is that the files in the file set are deleted, the response message is sent to the third-party application, so that the situation that the third-party application is damaged due to repeated sending of the deletion request message because the third-party application cannot acquire the response message in time is avoided, and the stability and the safety of the electronic equipment background processing of the file deletion request of the third-party application are improved.

The files associated with the third party application may be various files generated, cached, etc. by the third party application during use, such files being generated as a result of installation or operation of the third party application. Taking the above-mentioned files as picture files as an example, the pictures associated with the third-party application may be various pictures cached by the third-party application program in the using process, and the like. The picture not associated with the third-party application may be multimedia data shot by the user or multimedia data downloaded from the internet, and the generation of the part of the picture is irrelevant to the third-party application, and the deletion of the part of the picture by the third-party application may cause the loss of the multimedia data in the electronic device, and affect the normal use of the electronic device.
Therefore, whether a deletion request of the third-party application for the files is an illegal deletion request is judged by judging whether part of the deleted files is not associated with the third-party application, and the third-party application is prevented from directly and permanently deleting the target picture by transferring the files to a preset storage space under the condition that the deletion request of the third-party application for the files is judged to be the illegal deletion request.
In one embodiment, a specific implementation manner of the electronic device detecting that the deletion request of the third-party application for the plurality of files is an illegal deletion request may be:

And if the deletion requests of the third-party application for the files are judged to be illegal deletion requests, the files are transferred to a preset storage space, so that the third-party application is prevented from directly and permanently deleting the target picture.
In one embodiment, the electronic device may further perform the following:
when the recovery requests of the multiple files are detected, executing a transfer operation for the files in the ith file set, and simultaneously executing a file position scanning operation for the files in the (i + 1) th file set, wherein the file position scanning operation is used for acquiring the positions of the files in the (i + 1) th file set in the preset storage space so as to transfer the files in the (i + 1) th file set from the preset storage space to the original storage space.
