Description

File management method, device and computer readable medium

Technical Field

The present application relates to the field of information technology, and in particular, to a file management method, device, and computer readable medium.

Background

With the development of technology, electronic devices have become an indispensable device. When people use electronic equipment, various files are stored in the electronic equipment, and various application programs are installed in the electronic equipment so as to realize corresponding functions. For an electronic device, the larger the storage capacity is, the higher the cost is, and therefore the storage capacity of the device is generally limited. For example, for a mobile terminal, a conventional storage capacity is generally set to a fixed specification such as 64GB, 128GB, 512GB, etc., and if a user encounters insufficient capacity during use, the user may obtain a storage space by cleaning up unnecessary files.

At present, in the industry, when files are cleared, files needing to be cleared can be determined manually or automatically, for example, a user manually selects the files needing to be cleared in a file list or an electronic device automatically scans files which can be deleted according to a certain rule, after clearing is completed, the files cannot be deleted, and at this time, the available storage space in the user device is increased. However, this solution has the disadvantage that if the undesired files are inadvertently and incorrectly selected, the user cannot retrieve the corresponding files after the files have been cleaned. In order to avoid the problem of being unable to find back, an improved scheme is to backup the file before deleting the file, and store the file in another storage space, such as a recycle bin, a cloud storage device, and the like. When a user needs to retrieve a deleted file, the user needs to log in a backup storage space to search for a specific file, and the difficulty of searching increases with the increase of the number of backup files, so that the scheme solves the problem that the file cannot be retrieved, but the retrieval is difficult when the number of files is large, and the user experience is poor.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In a typical configuration of the present application, the terminal, the devices serving the network each include one or more processors (CPUs), input/output interfaces, network interfaces, and memory.

The memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium.

Computer-readable media, which include both non-transitory and non-transitory, removable and non-removable media, may implement the information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Disks (DVD) or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device.

The embodiment of the application provides a file management method, which can display a classification directory of deleted files, wherein the classification directory comprises the deleted files displayed according to classification information, and after a target file to be retrieved is detected to be selected by a user based on the displayed classification directory, the target file is acquired from network equipment, and the target file is locally restored at user equipment, so that even if the number of the deleted files is large, the user can quickly find out the specific deleted file by checking the classification directory, the quick retrieval of the file is realized, and the user experience is improved.

In a practical scenario, the execution subject of the method may be various types of user equipment, where the user equipment includes an input/output device for implementing interaction with a user, such as acquiring an operation and an instruction of the user, displaying related content to the user, and the like. The specific implementation of the user equipment may include, but is not limited to, various terminal devices such as a computer, a mobile phone, a tablet computer, and the like, or may also be an application program that can be run on the terminal device and implement corresponding processing logic.

Fig. 1 shows a processing flow of a file management method provided in an embodiment of the present application, where an execution subject of the method may be a user device, and processing logic corresponding to a relevant processing flow may be controlled and executed by an application running on the user device, and includes the following processing steps:

and step S101, determining the file to be deleted according to the cleaning instruction. The cleaning instruction may be an instruction for cleaning the storage space, which is manually input by a user, for example, an instruction triggered by the user manually selecting a file to be cleaned in a file list and clicking a cleaning button; or the instruction may be an instruction for automatically clearing the storage space triggered based on a preset condition, for example, when the storage space occupied in the user equipment reaches a preset value, a file that can be deleted is automatically scanned according to a set rule, and then a deletion instruction is triggered. Based on the cleaning instructions, files to be deleted can be determined, and after the files are deleted, the local storage space can be cleaned.

And step S102, sending the file to network equipment for storage, and deleting the file locally on the user equipment. Because the file to be deleted is sent to the network equipment for storage, even if the file is deleted locally by the user equipment, the backup of the file also exists in the network equipment, so that the problem that the file cannot be found back after the file which is not expected to be clear is deleted by mistake by accident can be avoided, and meanwhile, the backup file does not occupy the local storage space of the user equipment, so that the local storage space can be effectively cleaned.

Because data transmission between the user equipment and the network equipment needs to depend on a network environment, for example, when the network environment is not good, the transmission condition may not meet the requirement of file transmission, so that file transmission fails, and the network equipment cannot store files to be deleted. At this time, if the user device deletes the file locally, the user cannot retrieve the file deleted locally. Thus, in some embodiments of the present application, when sending the file to the network device for saving and deleting the file locally at the user device, a processing flow as shown in fig. 2 may be adopted, including:

step S201, determining whether the network environment meets the transmission condition. The network environment is determined based on a connection status, which may include, for example, the ability to connect to the network device and the inability to connect to the network device, a transmission speed, which is a speed of data transmission between the user equipment and the network device in the case of the ability to connect to the network device, and the like. In an actual scenario, it may be determined that the network device is capable of connecting to the network device and the transmission speed is greater than or equal to the preset value N, and it is determined that the network device is not capable of connecting to the network device, or it is capable of connecting to the network device and the transmission speed is less than the preset value N, and it is determined that the network device is not compliant with the transmission condition.

Step S202, if the transmission condition is met, it indicates that the file can be smoothly transmitted from the user equipment to the network equipment for saving, so that the file can be sent to the network equipment for saving, and the file can be deleted locally at the user equipment.

Step S203, if the transmission condition is not met, it indicates that the file may not be successfully transmitted from the user equipment to the network equipment for saving in the current network environment, so that the file may be cached locally in the user equipment, and then returned to step S201 for determination, until the transmission condition is met, the file is sent to the network equipment for saving, and the file is deleted locally in the user equipment. In an actual scenario, when a file is cached locally, the file may be deleted in an original storage path, and the file is uniformly stored in a preset storage path, such as a recycle bin, until a transmission condition is met, the cached file is sent to a network device for storage, and the file is deleted from the locally preset storage path.

When a file is sent to a network device for saving, if the file is already stored in the network device, if the file is still repeatedly sent, the resource is wasted. Therefore, in some embodiments of the present application, when the file is sent to the network device for saving and the user device deletes the file locally, the summary information of the file may be generated first, and the summary information may be obtained by calculation based on any hash algorithm, such as MD5, SHA256, and the like. The method comprises the steps that the data of the files are subjected to hash calculation to obtain summary information with small data volume, and the same files are identical in summary obtained based on the same hash algorithm, so that the summary information is sent to network equipment, and the network equipment can judge whether the files are stored or not according to the summary information.

For example, for the file d1 to be deleted, before sending it to the network device for saving, the user device may calculate its MD5 value, and provide the MD5 value to the network device, and the network device may determine whether there is a file with the same MD5 value in the files already stored therein, if so, it may determine that the file d1 is already saved in the network device, and if not, it may indicate that the file d1 is not saved in the network device. The network device may return the determination result to the user device, and the user obtains the determination result returned by the network device and performs subsequent processing based on the determination result. If the judgment result is yes, the file is directly deleted locally at the user equipment; if the judgment result is negative, the file is sent to the network equipment for storage, and the file is locally deleted at the user equipment.

Step S103, displaying the classified directory of the deleted files. The deleted files comprise files which are deleted locally in user equipment and stored by network equipment, the classification directory comprises the deleted files displayed according to classification information, and the classification information is determined according to attributes of the deleted files.

In an actual scenario, the attribute of the deleted file may include a file type, a local deletion time, and the like, and thus the classification information is determined according to the file type and/or the local deletion time of the deleted file. For example, common document type files such as PDF, Word, Excel, and PPT can be classified into one type according to file types, multimedia type files such as pictures, videos, and audios can be classified into one type, various types of installation packages can be classified into one type, other files can be classified into another type, files deleted on the same day can be classified into one type according to local deletion time, files deleted within one week can be classified into one type, files deleted within one week to one month can be classified into one type, and the like. In addition, the file type and the local deletion time can be combined, and after the file type is divided, and then the file type is subdivided or sorted according to the time under each classification. It will be understood by those skilled in the art that the above-described manner of determining classification information is by way of example only, and other forms based on similar principles, now existing or later to come, if applicable, are intended to be encompassed within the scope of the present application and are herein incorporated by reference.

In an actual scenario, when a deleted file is displayed in the classification directory according to the classification information, the file name and the icon of the deleted file may be displayed according to the classification of the classification information. Fig. 3 is a schematic diagram illustrating a category directory displayed to a user by a user device, wherein if the user needs to retrieve a certain erroneously deleted file, the user can quickly find a specific file through the category directory, so as to conveniently retrieve the erroneously deleted file. In addition, besides the file name and the icon, other descriptive contents about the file, such as the file size, the deletion time, the creation time, the modification time, the file creator, and the like, can be displayed, so that the user can find the file more conveniently.

The classification information of the deleted file can be determined by the user equipment, or can be determined by the network equipment and returned to the user equipment after being stored on the network equipment. Therefore, after the user equipment sends the file to the network equipment for storage, the network equipment can determine the classification information according to the attribute of the deleted file and return the classification information. At this time, the user device may acquire classification information on the deleted files from the network device and display a classification directory of the deleted files according to the classification information.

In some embodiments of the present application, the classification information may also be used to determine a degree of importance. For example, in a scenario in which classification information is divided according to file types, the classification information is a document class, a multimedia class, an installation package class, and other classes, respectively, a document class including files such as PDF, Word, Excel, and PPT may be used as a class with the highest importance, a multimedia class including files such as pictures, videos, and audios may be used as a class with the second highest importance, an installation package class may be used as a class with the third highest importance, and other classes may be used as a class with the lowest importance. Also for example, in a scenario in which classification information is divided according to local deletion time, the degree of importance of each category may be determined according to local deletion time, the closer the local deletion time, the higher the degree of importance. Thereby, the importance of the deleted file can be determined based on the classification information.

Based on the determined importance degree, when the classification directory of the deleted files is displayed, the deleted files in the classification directory can be displayed in a distinguishing manner according to the importance degrees of the deleted files. The purpose of the distinguishing display is to enable a user to visually distinguish the importance degrees of different deleted files after seeing the classification directory, for example, the specific form of the distinguishing display may be a display with different colors, or a priority display of deleted files with high importance degrees, and the like. It will be understood by those skilled in the art that the specific forms shown and described are by way of example only and that other forms, whether now known or later developed based on similar principles, are also within the scope of the present application and are herein incorporated by reference.

Taking the foregoing classification directories displayed according to the classification information of the document class, the multimedia class, the installation package class, and the other classes as an example, the file name of the deleted file of the document class may be displayed with a red font, the file name of the deleted file of the multimedia class may be displayed with a yellow font, the file name of the deleted file of the installation package class may be displayed with a blue font, and the file name of the deleted file of the other classes may be displayed with a black font. Therefore, the user can intuitively judge the importance degree of the deleted file through the display color of the file name so as to search for the specific file.

And step S104, after detecting that the target file needing to be retrieved is selected by the user based on the displayed classified catalogue, acquiring the target file from the network equipment, and locally restoring the target file in the user equipment. The user equipment displays the classification catalog of the deleted files, so that the user can check the classification catalog through the user equipment, and if the user deletes a certain file by mistake and needs to retrieve the file, the user can execute corresponding operation on the classification catalog to select a target file needing to be retrieved. Therefore, even when the number of the deleted files is large, the user can quickly find the specific deleted files by checking the classified directory, so that the files can be quickly found back, and the user experience is improved.

In an actual scene, when a user selects a target file to be retrieved based on a displayed classification directory, a deleted file in the classification directory can be clicked through an input device such as a mouse or a touch screen, and the clicked deleted file is the selected target file. After the post-target file is selected, the retrieving operation may be triggered in a preset manner, for example, a confirmation button of the retrieving operation is clicked or a specific gesture operation is input. After the retrieving operation is triggered, the user equipment may acquire the target file from the network device, and locally restore the target file at the user equipment, thereby completing retrieving the target file.

In addition, in addition to retrieving the target file, the scheme provided by the embodiment of the present application may also completely delete the target file, that is, delete the file stored in the network device. Therefore, the file management method provided by the embodiment of the application may further include: and requesting the network equipment to delete the stored target file after detecting that the user selects the target file to be deleted based on the displayed classification directory.

When a user selects a target file to be deleted based on the displayed classification directory, the deleted file in the classification directory can be clicked through an input device such as a mouse or a touch screen, and the clicked deleted file is the selected target file. After the selected target file is selected, a complete deletion operation may be triggered in a preset manner, for example, a confirmation button of the complete deletion operation is clicked or a specific gesture operation is input. After triggering the complete deletion operation, the user equipment may send corresponding information to the network equipment, requesting the network equipment to delete the saved target file.

To further ensure the security of the files stored in the network device, the files may be associated with the source identifier. Therefore, when the user equipment sends the file to the network equipment for saving, the user equipment can send the file and the source identification to the network equipment, so that the network equipment marks the source of the file according to the source identification when saving the file. The source identifier is used to identify the source of the file, thereby restricting operations on the file by instructions from other sources.

In some embodiments of the present application, when the target file is obtained from the network device and the target file is locally restored by the user equipment, a recovery request may be sent to the network device. The retrieve request includes a file identifier of the target file and a source identifier, where the file identifier may be any information that can uniquely point to the file, such as a file name, an MD5 value corresponding to the file, and the like. The source identifier is information for determining the source of the request, and may be a user ID or a device ID, for example. For example, the source identifier may be a user ID or an equipment ID, and if the user ID is used, the source identifier is also carried when the user equipment uploads a file to the network equipment for backup storage. When the network device saves the file, the source of the file is marked according to the user ID, which indicates that the file comes from a certain user 1. If the device ID is used, the network device, when saving the file, marks the source of the file according to the device ID, indicating that the file is from a certain user equipment UE 1.

Therefore, the network device determines the target file corresponding to the retrieval request according to the file identifier and the source identifier in the retrieval request, for example, the network device may first search in the stored file according to the file identifier in the retrieval request, if the file with the same file identifier can be found, further retrieve the total source identifier of the request and the source identifier of the file, and if the two identifiers are consistent, send the file back to the user device as the target file. Therefore, the user receives the target file returned by the network equipment and restores the target file locally on the user equipment. For example, if the source of the file d1 stored in the network device is identified as user ID user1, and if the file name of the target file to be retrieved in the retrieval request sent by the user device is d1, but the source is identified as user2, the target file d1 cannot be retrieved from the network device. Therefore, the security of the deleted files in the network equipment can be improved, and the deleted files are prevented from being acquired by other users.

Fig. 4 shows a processing flow when file cleaning is implemented by using a scheme of an embodiment of the present application, including the following processing steps:

step S401, the user selects the junk files needing to be cleaned in the user equipment.

Step S402, the user equipment judges whether the user equipment can be connected to the network equipment, if not, step S403 is executed, if yes, step S404 is executed

Step S403, cache the garbage file locally, and return to step S402.

Step S404, determining whether the network device stores the junk file to be uploaded. The garbage files to be uploaded comprise newly selected garbage files and garbage files which are temporarily not uploaded and are cached locally. The step S406 is directly executed for the junk files already stored in the network device without uploading, and the step S405 is executed for the junk files not stored in the network device.

And step S405, uploading the junk files, and performing associated storage according to the device ID, the user ID and the like.

In step S406, the user equipment performs a local deletion operation.

Step S407, judging whether the deletion is successful, and prompting the user that the deletion is successful or failed according to the result.

Step S408, displaying the classification directory of the junk files. The user can quickly search for the needed junk files based on the displayed classification directories, for example, if the mistakenly deleted junk files need to be retrieved, the target files needing to be retrieved can be selected from the classification directories.

Step S409, after detecting that the user selects the target file to be retrieved based on the displayed classified directory, the user equipment acquires the target file from the network equipment and locally restores the target file in the user equipment. In addition to retrieving files, the user may also completely delete files uploaded to the network device.
