Before the steps of this embodiment are executed, a mapping form needs to be preset in the terminal, where each file is recorded as a file attribute, where the file attribute includes: file occupation space and file time information, wherein the file time information comprises: file creation time, file access time, file modification time and the like, and when the storage space of the terminal is released, the terminal releases the storage space according to a preset mapping form, specifically:
referring to fig. 3, a first embodiment of the present invention provides a terminal storage space management method, including:
step S10, monitoring the free space of the storage space, and comparing the free space with a preset space threshold.
The terminal detects the free space of the storage space in real time, and compares the free space with a preset space threshold, wherein the preset space threshold is a preset free space threshold, and when the free space is larger than or equal to the preset space threshold, the terminal is not affected too much; conversely, when the free space is smaller than the preset space threshold, if the user may operate the terminal and the storage space of the terminal is insufficient, the preset space threshold in this embodiment may be a specific size (e.g. 50M, 100M, etc.), or may be a percentage (e.g. 5%, 10%, etc.) of the whole storage space.
The terminal determines whether to release the storage space of the terminal, that is,
and step S20, inquiring a preset mapping form when the free space is smaller than the preset space threshold value, and determining the target file to be processed in the storage space.
When the terminal determines that the free space is smaller than the preset space threshold, the terminal inquires a preset mapping form and obtains file attributes of all files in the preset mapping form; the terminal calculates the file score of the file corresponding to the file attribute according to the file attribute of each file in the preset mapping form, and determines the target file to be processed when the storage space of the terminal is released according to the file score, and specifically comprises the following steps:
step a, obtaining a file type in the file attribute, and obtaining a file occupation space, a file creation time, a file access time and a file modification time in the file attribute when the file type is a preset processing type.
And b, inquiring a preset score mapping table, obtaining attribute scores corresponding to the file occupation space, the file creation time, the file access time and the file modification time, and summing the attribute scores to obtain the file scores of the files corresponding to the file attributes.
The terminal acquires the file types in the file attributes, namely, when the storage space of the terminal is released, the terminal only processes part of the types of files, and the terminal takes the processable file types as preset processing types (the preset processing types are preset file types which can be released, such as network resources, local caches and local data).
When the terminal determines that the file type is a preset processing type, the terminal acquires file occupation space and file time information in file attributes, wherein the file time information comprises: file creation time, file access time, and file modification time. The terminal inquires a preset grading mapping table (attribute grades corresponding to different file attributes are set in the preset grading mapping table), obtains the attribute grades corresponding to the file occupation space, the file creation time, the file access time and the file modification time, and adds the attribute grades to obtain the file grade of the file corresponding to the file attribute.
The terminal compares the obtained file scores of the files with preset standard scores, wherein the preset standard scores are preset score critical values, and the terminal takes the file with the file score lower than the preset standard score as a target file to be processed in the storage space. In this embodiment, the terminal determines the score of the file according to the information in the preset score mapping table, so as to accurately screen the target processing file, and meanwhile, avoid the situation that the file required by the user in the terminal is deleted.
Step S30, determining a processing mode of the target file, and processing the target file according to the processing mode and the preset mapping form to release the storage space.
After obtaining the target file, the terminal determines a processing mode of the target file, wherein the processing mode can be an automatic compression mode, an automatic transfer mode, an automatic deletion mode or the like, and the storage space is released by processing the file in the storage space by adopting the processing mode. When the processing mode is set, the processing mode may be directly set to an automatic compression mode, an automatic transfer mode, an automatic deletion mode, or the like.
Preferably, the terminal outputs the processing modes such as the automatic compression mode, the automatic transfer mode, the automatic deletion mode and the like for the user to select, and then the terminal sets the processing mode according to the user selection. The user may further choose to determine the processing order (compression order, transfer order, deletion order, etc.) according to the storage time, size, or type of data. Preferably, the terminal may also provide two or more processing methods of the automatic compression method, the automatic transfer method, the automatic deletion method, and the like to the user at the same time, for example, if the automatic compression method and the automatic transfer method are provided to the user at the same time, the terminal determines to submit the automatic compression method to perform the file compression process or to perform the file transfer process by the automatic transfer method according to the file attribute of the target file.
The automatic compression mode is to compress data by using a preset compression algorithm. The automatic transfer mode refers to that data is moved out of the storage space of the terminal, and the data can be transferred to a network space (such as a network hard disk, a mailbox and the like) through the internet, or transferred to other devices through a wireless communication mode (such as NFC, bluetooth, WIFI) and the like.
After the terminal determines the processing mode of the target file, referring to fig. 4, the terminal processes according to the determined processing mode, and queries the storage position of the target file in the preset mapping form to process the target file, and finally releases the storage space of the terminal. In the embodiment, a processing mode of the target file and the target file which can be processed is determined, and the target file is processed according to the processing mode, so that the storage space is released rapidly and accurately.
Further, on the basis of the above embodiment, a second embodiment of the terminal storage space management method of the present invention is provided.
In this embodiment, the step of determining the processing manner of the target file by the terminal and releasing the storage space according to the determined processing manner is described, which specifically includes:
step S31, a preset release threshold corresponding to the free space is obtained, and the file occupation space of the target file is compared with the preset release threshold.
The terminal inquires a preset release space table, wherein the preset release space table comprises preset release thresholds corresponding to different free space ranges, for example, when the free space in the preset release space table is 50M to 100M, the corresponding preset release threshold is 100M; and when the free space is 100M to 150M, the corresponding preset release threshold value is 50M, and the terminal acquires the corresponding preset release threshold value of the free space.
After the terminal obtains a preset release threshold, the terminal compares the file occupation space of the target file with the preset release threshold, and determines a processing mode of determining the target file according to a comparison result, specifically:
step S32, when the file occupation space of the target file is smaller than or equal to the preset release threshold, determining that the processing mode of the target file is a deletion mode.
When the terminal determines that the file occupation space of the target file is smaller than or equal to the preset release threshold, namely, more space needs to be released by the terminal and less occupied space of the target file, the terminal sets the processing mode of the target file as a deleting mode.
Step S33, obtaining the storage position of the target file in a preset mapping form, and deleting the target file in the storage position to release the storage space.
The terminal obtains the storage position of the target file in the preset mapping form, referring to fig. 5, the terminal deletes the target file in the storage position to release the storage space, and in this embodiment, the processing of the target file is performed according to the storage position of the target file in the preset mapping form, so that the processing efficiency of the file can be accelerated.
It should be noted that, after the terminal processes the target file according to the processing manner, there may be less storage space released by the terminal, so the terminal returns to execute the step of step S10 in this embodiment, the terminal compares the new space with the preset space threshold, and when the terminal determines that the free space is smaller than the preset space threshold, the terminal can release the storage space for the second time.
Step S34, when the file occupation space of the target file is greater than the preset release threshold, determining that the processing mode of the target file is a compression mode.
When the terminal determines that the file occupation space of the target file is larger than the preset release threshold, namely, the space required to be released by the terminal is less, and the occupation space of the target file is more, if the target corpus is directly deleted, part of useful files can be deleted, and therefore, the terminal sets the processing mode of the target file as a compression mode.
Step S35, obtaining a storage location of the target file in a preset mapping form, and compressing the target file in the storage location to release the storage space.
The terminal acquires a storage position of a target file in a preset mapping form, and compresses the target file in the storage position to release the storage space. In this embodiment, the terminal processes the target file in a compression manner, and the terminal may decompress the target file, so that the target file is reused.
It should be noted that, in this embodiment, other processing manners may be determined according to other attribute information in the file attribute, for example, the transfer of the target file is determined according to the file time information of the target file, which is not described in detail in this embodiment, and in this embodiment, the processing manner of the target file is determined according to the file attribute, so that automatic processing of the target file can be implemented without manual operation of a user, and meanwhile, the rationality of file processing is ensured.
Further, referring to fig. 6, a third embodiment of the terminal storage space management method according to the present invention is provided on the basis of the above-mentioned embodiment.
In this embodiment, a method for updating a file attribute in a preset mapping form is described, which specifically includes:
Step S40, receiving a file preservation request, and obtaining a file to be preserved in the file preservation request and file attributes of the file.
The terminal receives a file saving request, wherein the triggering mode of the file saving request is not particularly limited, for example, a user may manually save a new file and trigger the file saving request; or when a user browses videos, a new cache file appears, a file saving request is triggered, and after the terminal receives the file saving request, the terminal acquires a file to be saved in the file saving request and file attributes of the file, wherein the file attributes comprise file types, file occupied spaces, file storage positions and file time information.
Step S50, adding the file attribute to the preset mapping form to update the preset mapping form.
The terminal adds the file attribute into the preset mapping form according to the header of the preset mapping form so as to update the preset mapping form. In this embodiment, the terminal adds the new file attribute information to the preset mapping table, and manages the new file according to the preset mapping table by updating the preset mapping table, so as to finally realize management of the storage space of the terminal, that is, when the storage space of the terminal is released, the terminal can process the new file through the updated preset mapping table.
Further, referring to fig. 7, a fourth embodiment of the terminal storage space management method according to the present invention is provided on the basis of the above-mentioned embodiment.
The embodiment is a refinement after step S30 in the first embodiment, in which the terminal determines, according to a release manner of the storage space, a processing method of a file attribute in a preset mapping form, and specifically includes:
and step S60, when the completion of the release of the storage space is detected, determining whether the processing mode of the target file is file deletion.
After the terminal finishes releasing the storage space, the terminal determines whether the processing mode of the target file is file deletion or not when the storage space is released.
Step S70, deleting the file attribute of the target file in the preset mapping form when the processing mode of the target file is file deletion.
When the terminal determines that the processing mode of the target file is file deletion, the terminal deletes the file attribute of the target file in a preset mapping form; in this embodiment, when the terminal determines that the storage space is managed by deleting, the terminal also needs to delete the file attribute related to the target file in the preset mapping form, so that the terminal is faster when querying the preset mapping form.
Further, referring to fig. 8, a fifth embodiment of the terminal storage space management method according to the present invention is proposed on the basis of the above-mentioned embodiment.
In this embodiment, the terminal pre-alarms the threshold, and the terminal prompts the user according to the preset alarm threshold, specifically including:
