Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, result, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The electronic device according to the embodiment of the present application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of User Equipment (UE), Mobile Stations (MS), terminal devices (terminal device), and so on. For convenience of description, the above-mentioned apparatuses are collectively referred to as electronic devices. The operating system related to the embodiment of the invention is a software system which performs unified management on hardware resources and provides a service interface for a user.
Referring to fig. 1A first, in fig. 1A, a file processing method provided by an embodiment of the present application is applied to an electronic device, and the method includes:
and step S101, receiving a deletion request of the target folder.
The target folder may be a folder under the gallery directory, where the directory name corresponding to the target folder may be: cameras (Camera), Screenshots (Screenshots), WeChat, QQ and the like, and the files in the target folder can be various files such as pictures, texts, audios and videos.
The deletion request of the third-party application is specifically a deletion request for deleting the target folder caused by a system error when the third-party application is installed, uninstalled or cleared of the data cache of the third application, the electronic device may be in a screen-off state when the deletion request is generated, and the deletion request may be generated when the third-party application runs in the background and performs related operations.
And step S102, creating a temporary file in the target folder, and deleting the temporary file when the deletion request is a deletion request of a third-party application.
Optionally, the creating a temporary file in the target folder specifically includes the following steps: after receiving the deletion request, acquiring a deletion sequence of the target folder, namely a deletion sequence of files in the target folder, wherein the deletion sequence is generally a deletion sequence according to file names, a deletion sequence according to file creation time, a deletion sequence according to a file memory or a deletion sequence according to the use heat of the files; the file attributes of the files in the target folder and the deletion sequence, such as the folders in the gallery, are obtained, and the files in the gallery folder are generally deleted according to the sequence of the creation time, that is, when any one folder in the gallery is deleted, the file with the earliest creation time in the folder is deleted firstly, and then all the files in the folder are deleted in sequence according to the sequence of the creation time. Therefore, the creation time of each file in the target folder is obtained, the temporary file is created according to the creation time of each file, namely, the creation time of the temporary file is set to be the earliest, the temporary file is ensured to be positioned at the first position in a deletion list corresponding to the deletion sequence, namely, the temporary file is deleted firstly when the target folder is deleted by a third-party application.
Step S103, executing the deletion request, and if it is detected that the temporary file is deleted, executing a protection operation, where the protection operation is used to retain the remaining files in the target folder when the deletion request is executed.
Optionally, the protection operation may be preset, and is specifically configured to protect remaining files in the target folder from being permanently deleted when the third-party application deletes the target folder.
Further, executing the protection operation specifically includes the following steps: after the temporary file is deleted, the deletion request for the remaining file in the deletion request is ignored, that is, the remaining file is not deleted, and since the deletion request is a deletion request of a third-party application, subsequent operations of the third-party application cannot be executed. The reason is that a multi-step operation is required to execute the current function of the third application, wherein the target folder is deleted as one step in the multi-step operation, and the next operation must be executed based on the completion response of the previous operation, so that when the deletion request for the remaining files in the deletion request is ignored, the operation of deleting the target folder is not completed, and the subsequent operation of the third application cannot be executed.
The subsequent operation of the third-party application may be various, and specifically relates to a function that the third-party application is currently running, if the third-party application is executing version update, the version update process needs to execute multi-step operations, where deleting the target folder is one step of the multi-step operations, and the operation after deleting the target folder is the subsequent operation.
Further, after the deletion request for the remaining files in the deletion request is ignored, the access right of the third-party application to the target folder is closed to obtain a closing response, and the closing response is fed back to the third-party application so as to execute the subsequent operation of the third-party application. Certainly, the access permission of the third-party application to the target folder may be actively closed by the user, that is, after the deletion request is ignored, since the third party has not received the deletion response all the time, the third-party application cannot perform subsequent operations, and the user needs to be prompted to close the access permission of the third-party application to the target folder.
For example, as shown in fig. 1B, if a delete request for deleting an album is generated when a microblog is unloaded, since the delete request for deleting the album is ignored, execution of the delete album operation in the unloading function fails, which results in failure of unloading the microblog, a prompt box pops up after the unload failure, sends out prompt information, prompts a user to unload the microblog again after closing the access right of the microblog to the album, and can unload the microblog, where the prompt information is specifically "unload failure, please close the access right of the microblog to the album before unloading the microblog".
It can be seen that, in the embodiment of the present application, after receiving a deletion request of a target folder, a temporary file of the target folder is created, a file attribute of the temporary file is modified to be only deleted by a third-party application and not visible to a user, if the temporary file is deleted, the deletion request is determined to be a deletion request of the third-party application, the deletion request for the remaining files in the target folder is ignored, and the access right of the third-party application to the target folder is closed, so as to complete subsequent operations of the third-party application, thereby solving the problem of mistakenly deleting the target folder when executing the current function of the third-party application, protecting user data, and improving user experience.
Referring to fig. 2, fig. 2 is a diagram of another file processing method provided in an embodiment of the present application, where the method is applied to an electronic device, and the method includes the following steps:
step S201, a deletion request of the target folder is received.
Step S202, a temporary file is created in the target folder, and the temporary file is deleted when the deletion request is a deletion request of a third-party application.
Step S203, executing the deletion request, copying the remaining files in the target folder to a preset storage space if the deletion of the temporary file is detected, continuing to respond to the deletion request for the remaining files in the deletion request after the copying is completed, and deleting the remaining files according to the deletion sequence to obtain a first deletion response.
The preset storage space may be a preset storage space dedicated to caching data, and specifically, the preset storage space may be a hidden recycle bin configured to receive a file transferred from the target folder.
Optionally, copying the remaining files in the target folder to a preset storage space includes: after the temporary file is deleted, if the residual file is not completely copied to the preset storage space, the copying operation is suspended, the first temporary file is re-created, and when the deletion of the first temporary file is executed, the residual file is continuously copied until the residual file is copied to the preset storage space or the total memory and the copying speed of the residual file are acquired; determining the copying duration of the residual files according to the total memory and the copying speed; acquiring a deleting time length required for deleting a temporary file; and determining a first number of the needed temporary files according to the deleting duration and the copying duration, and creating the temporary files of the first number in the target folder, so that after the temporary files of the first number are deleted, all the residual files are copied to the preset storage space.
Step S204, feeding back the first deletion response to the third-party application so as to continue to execute subsequent operations of the third-party application, and restoring the remaining files from the preset storage space after detecting that the subsequent operations are completed.
The subsequent operations of the third-party application may be various, and are specifically related to the currently running function of the third-party application, for example, if the third-party application is being uninstalled, the uninstalling process needs to perform a multi-step operation, where deleting the target folder is one step of the multi-step operation, and the operation after deleting the target folder is the subsequent operation.
It can be seen that, in this embodiment, when it is determined that the deletion request is a deletion request of the third-party application, after deleting the temporary file, first transferring the remaining files in the target folder to a preset storage space, then deleting the remaining files, that is, deleting the target folder to obtain a deletion response, and feeding back the deletion response to the third-party application, so that the third-party application executes subsequent operations, thereby ensuring smooth execution of the current running function of the third-party application while protecting data in the target folder; moreover, the whole process of transferring the residual files is operated in the background, so that the user cannot perceive the residual files, and the user experience is improved.
Optionally, in a possible example, in terms of protecting the remaining files in the target folder from being permanently deleted, the method further includes:
and if the total memory is larger than a threshold value, selecting one file from the remaining files each time according to the deletion sequence, copying the file to a preset storage space, deleting the file from the remaining files after the file is copied, obtaining a second deletion response after the copying and deleting operation of the last file in the remaining files are detected to be completed, feeding the second deletion response back to the third-party application so as to continue to execute the subsequent operation of the third-party application, and restoring the remaining files from the preset storage space after the execution of the subsequent operation is detected to be completed.
The threshold may be 1GB, 2GB, 3GB, or another value.
The restoring of the remaining files may be performed according to a deletion order during deletion, or may be performed randomly, where the restoration order is not limited herein.
It can be seen that, in this example, first, the total memory of the remaining files is obtained, if the total memory is greater than the threshold, if the remaining files are copied to the preset storage space together, a memory space as large as the total memory of the remaining files needs to be reserved for the preset storage space, at this time, the storage space of the preset storage space and the total memory of the remaining files will occupy a large amount of memory of the electronic device, since the memory of the electronic device is limited, and too much storage space cannot be allocated for the preset storage space, so that the remaining files cannot be copied completely or copy fails, when the memory of the target folder is large, this way of copying together is no longer applicable, in this example, the remaining files are copied to the preset storage space in sequence, only one file is copied each time, and the file is deleted after the copying is completed, so that after the target folder is copied to the preset storage space, the memory occupied by the target folder is released, so that the sequential copying mode does not need to reserve a storage space for the preset storage space, the memory pressure of the electronic device is reduced, the problem that the residual files cannot be completely copied or the copying fails when the target folder is large is solved, and the memory pressure of the electronic device is relieved.
Referring to fig. 3, fig. 3 is a diagram of another file processing method provided in an embodiment of the present application, where the method is applied to an electronic device, and the method includes:
step S301, when a deletion request for a target folder is received, a temporary file is created in the target folder.
Step S302, executing the deletion request, and if the temporary file is deleted, obtaining a total memory of the remaining files in the target folder, and if the total memory is greater than a threshold, compressing the remaining files according to a preset compression rule to obtain a compressed file.
Step S303, copying the compressed file to a preset storage space, deleting the target folder to obtain a deletion response, feeding back the deletion response to the third-party application to execute a subsequent operation of the third-party application, restoring the compressed file from the preset storage space after the subsequent operation of the third-party application is completed, and decompressing the file to obtain the target folder.
The preset storage space may be a preset storage space dedicated to caching data, and specifically, the preset storage space may be a hidden recycle bin configured to receive a file transferred from the target folder.
It can be seen that, in the embodiment of the present application, when it is determined that a third-party application deletes a target folder, first, a memory of the target folder is detected, if the memory is greater than a threshold, the target folder is compressed to obtain a compressed file to reduce the memory of the target folder, the compressed file is transferred to a preset storage space, the target file is deleted to obtain a deletion response, the deletion response is fed back to the third-party application to execute a subsequent operation of the third-party application, and after the completion of the subsequent operation is detected, the compressed file is restored and the compressed file is decompressed to obtain the target folder.
