Description

Method and system for organizing device cache files

technical field

The present application relates to the fields of data integration and data optimization, and in particular, relates to a method and system for sorting out device cache files.

Background technique

At present, with the high maturity of multimedia technology and network information dissemination technology, playing and browsing multimedia videos through the network has already become the habit of thousands of users. Network video fully meets the diverse needs of users for work, entertainment and learning. Watching online video is a widely familiar way of life.

When users watch online videos, especially when they use the application program (APP) of the video website to watch online videos; they can watch online directly, cache and browse instantly; they can also pre-cache video files to the built-in storage of the device, so that they can be saved when the device is not in use. Browse when connected to the network or when the network status is poor. Video files pre-cached to the built-in storage will occupy the corresponding storage space.

For mobile devices, in most cases, the built-in storage space is more than a dozen or tens of GB; even for large-capacity mobile devices on the market, the storage space is at most about a hundred GB. So if the application saves a large number of cache files, it may cause insufficient storage space.

Many users do not have the habit of actively deleting cache files. When the storage space is insufficient and the application program cannot cache new video files, it often only gives a "insufficient space" prompt, and does not guide the user to delete the previous cached file. If the user does not know how to delete the cache file, he cannot continue to cache other videos, affecting normal video viewing and reducing user experience. Therefore, the defect of the prior art is that there is no effective method for organizing cached files.

Contents of the invention

In view of this, the technical problem to be solved by this application is to provide a method and system for organizing device cache files. When the storage space is insufficient, the user is guided to delete some of the previous cache files to achieve the purpose of clearing the storage space.

In order to solve the above technical problems, the application has the following technical solutions:

A method for organizing device cache files, comprising:

When the device specifies a file to be cached, it is judged whether the volume of the file to be cached is larger than the current remaining storage space of the device; if the volume of the file to be cached is larger than the remaining storage space, the volume of the file to be cached The difference between the remaining storage space is used as supplementary space;

According to preset screening rules, filter one or more cached cache files as files to be cleaned; the volume of the files to be cleaned is not less than the supplementary space; add the files to be cleaned to the list to be cleaned, and The list to be cleaned up is displayed;

When the device generates a delete instruction for the list to be cleaned, delete the file to be cleaned in the list to be cleaned according to the delete instruction;

Start caching the specified file to be cached.

The adding the file to be cleaned up to the list to be cleaned up, and displaying the list to be cleaned up also includes:

When the device generates an extended instruction for the list to be cleaned, it again filters one or more cached cache files as files to be cleaned according to preset filtering rules; and adds the files to be cleaned up to the list to be cleaned.

According to the preset filtering rules, filtering one or more cached cache files as files to be cleaned up is specifically:

According to the chronological order of cache completion, filter one or more cached cache files that complete cache first as files to be cleaned.

According to the preset filtering rules, filtering one or more cached cache files as files to be cleaned up is specifically:

According to the chronological order of finishing browsing, filter one or more cached cache files that are browsed last as files to be cleaned.

According to the preset filtering rules, filtering one or more cached cache files as files to be cleaned up is specifically:

One or more cached cache files with the lowest browsing frequency are filtered out as files to be cleaned.

According to the preset filtering rules, filtering one or more cached cache files as files to be cleaned up is specifically:

Filter out one or more cached cache files with the largest volume as files to be cleaned.

A system for organizing device cache files, comprising:

A space judging module, used to determine whether the volume of the file to be cached is greater than the current remaining storage space of the device when the device specifies the file to be cached; if the volume of the file to be cached is greater than the remaining storage space, the file to be cached The difference between the volume of the file and the remaining storage space is used as supplementary space;

The screening management module is used to filter one or more cached cache files as files to be cleaned according to preset screening rules; the volume of the files to be cleaned is not smaller than the supplementary space; and the file to be cleaned is added to the file to be cleaned Clean up the list, and display the list to be cleaned up;

A file cleaning module, configured to delete the files to be cleaned in the list to be cleaned according to the deletion instruction when the device generates a deletion instruction for the list to be cleaned;

Detailed ways

Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electrically coupled to the second device, or indirectly electrically coupled through other devices or coupling means. connected to the second device. The subsequent description of the specification is a preferred implementation mode for implementing the application, but the description is for the purpose of illustrating the general principle of the application, and is not intended to limit the scope of the application. The scope of protection of the present application should be defined by the appended claims.

In this application, when the user needs to make the device cache new cache files, but the storage space is insufficient, a list to be cleaned up will be displayed to guide the user to delete some of the previous cache files to achieve the effect of cleaning up the storage space; to ensure that the new The cached files can be successfully saved to the built-in storage of the device. Referring to FIG. 1 , it is a method for sorting out device cache files described in this application. The method described in this embodiment includes the following steps:

Step 101. When the device specifies a file to be cached, determine whether the volume of the file to be cached is greater than the current remaining storage space of the device; The difference with the remaining storage space is used as supplementary space.

In this embodiment, it is assumed that the user specifies a file A with a volume of 1.5 GB as the file to be cached through the device. Inevitably, more than 1.5GB of storage space needs to be reserved in the device, so that the file to be cached can be cached, otherwise it means that the storage space is insufficient.

After specifying the file to be cached, it is read that the remaining storage space of the current device is 0.9GB, and the volume of the file to be cached is larger than the current remaining storage space of the device, indicating that the current storage space is insufficient, and the caching of the file A to be cached cannot be completed. At this time, the difference between the volume of the file to be cached and the remaining storage space of 1.5-0.9=0.6 GB is used as the supplementary space. The supplementary space also means that at least 0.6 GB of space must be cleared in the device storage to realize the caching of the file A to be cached.

Step 102: Screen one or more cached cache files as files to be cleaned according to preset screening rules; the volume of the files to be cleaned is not smaller than the supplementary space; add the files to be cleaned to the list to be cleaned, And display the list to be cleaned up.

When the storage space of the device is insufficient, it generally means that the device has cached a large number of cache files before, and they have not been sorted or deleted in time, thus occupying too much space. In this embodiment, in order to actively guide the user to complete the arrangement of the storage space in this case, one or more files to be cleaned will be automatically selected from the previously cached cache files for the user to selectively delete. Clear out storage space. It has been calculated above that the supplementary space is 0.6GB, so the volume of the selected files to be cleaned must not be smaller than the above 0.6GB, so that after deleting the files to be cleaned, the problem of insufficient storage space can be solved.

The screening of the files to be cleaned is based on screening rules, and the basic principle of the screening rules is to screen out cache files that are no longer needed by the user as files to be cleaned as much as possible. You can refer to the following ways:

a. According to the chronological order of cache completion, filter one or more cached cache files that are cached first as files to be cleaned.

That is, according to the chronological order, it is considered that the earlier the cache is completed, the longer it is stored in the device, and it is most likely that it will no longer be needed by the user, and you can choose to delete it first.

b. According to the chronological order of browsing completion, filter one or more cached cache files that have been browsed last as files to be cleaned.

That is, according to the same chronological order, it is considered that the cache files that have been browsed recently, since the browsing has been completed, are most likely to be no longer needed by the user, so it is preferred to delete them.

c. Filter out one or more cached cache files with the lowest playback frequency as files to be cleaned.

That is to say, the low browsing frequency means that the user's demand is low, and it can be deleted first.

d. Filter out one or more cached cache files with the largest volume as files to be cleaned.

This method no longer starts from the perspective of the degree of user demand, but instead screens out cache files that occupy a large space and deletes them first, so as to clean up as much space as possible.

Any of the above methods can be used alone as the screening rule in this embodiment, or can be combined with each other in any manner as the screening rule in this embodiment. In addition, other similar screening methods can also be incorporated into the overall technical solution of this embodiment as screening rules. In short, there is no specific limitation on the content of the filtering rules in this embodiment.

Assuming that in this embodiment, mode a is selected as the screening rule, the three cache files B, C, and D that have been cached the earliest are screened out. The volumes of the three are 0.2GB, 0.3GB, and 0.5GB respectively, and the total is 1GB, which is greater than For the supplementary space, these three are used as files to be cleaned up and added to a list to be cleaned up.

Subsequently, the to-be-cleaned list is displayed to the user, and the user can learn information related to the file names and file volumes of each selected file to be cleaned, and decide whether to delete the to-be-cleaned file. The user can directly input an instruction to the list to be cleaned up to delete the files to be cleaned up.

In this embodiment, the so-called actively guiding the user to clean up the storage space is in essence to automatically display a list to be cleaned up to the user, so that the user can directly operate on the list to be cleaned up, avoiding the manual search for the directory of the cached file; It also prevents the situation that the user forgets to clean up the storage space, or does not know how to clean up the storage space.

Preferably, this step can also include here:

Step 102a: When the device generates an extended instruction for the list to be cleaned, it again filters one or more cached cache files as files to be cleaned according to preset filtering rules; and adds the files to be cleaned up to the list to be cleaned up.

That is to say, if the user does not want to delete the files to be cleaned up for the first time, or the user only wants to delete some of the files to be cleaned up, and the volume of these files to be cleaned up is smaller than the supplementary space, the user can also get more to be cleaned up through the extension command file, and then make a manual selection.

For example, in this embodiment, among the filtered files B, C, and D to be cleaned up, the user wishes to keep the file D to be cleaned up. However, the sum of the volumes of files B and C to be cleaned up is 0.5GB, which is less than the supplementary space. At this time, the user will input an extended command through the device, and then filter new files to be cleaned up again according to the preset filtering rules, that is, re-screen out the file E to be cleaned up with a volume of 0.9GB, and add it to the list to be cleaned up.

The principle of filtering the files to be cleaned up again according to the preset filtering rules is the same as that of filtering the files to be cleaned up in step 102, and the description will not be repeated here.

Step 103, when the device generates a deletion instruction for the list to be cleaned, delete the files to be cleaned in the list to be cleaned according to the deletion instruction.

The user can manually choose to delete those files to be cleaned in the list to be cleaned up, directly operate the list to be cleaned up, input a delete command, and delete any one or more files to be cleaned up in the list to be cleaned up. In this embodiment, the user can delete only the file E to be cleaned up, or delete all the files B, C, and E to be cleaned up, all of which can achieve the purpose of clearing up enough storage space.

Step 104, start caching the designated file to be cached.

When the storage space not less than the size of the supplementary space is cleared, the designated files to be cached can be started to be cached.

It can be seen from the above technical solutions that the beneficial effects of this embodiment are: using the screening rules, pre-filtering cache files with low demand and appropriate volume for the user as files to be cleaned; and by displaying the list to be cleaned to the user, Guide the user to directly operate on the list to be cleaned up to achieve the purpose of cleaning up the storage space; avoid the process of manually searching for the directory of the cached file in the existing storage space cleaning process, and also prevent the user from forgetting to clean up the storage space, or It happens that I don't know how to clean up storage space.

The system described in this embodiment is used to implement the method described in the embodiment shown in FIG. 1 . The technical solution of the system is essentially consistent with the method embodiment shown in FIG. 1 , and the corresponding descriptions in the embodiment shown in FIG. 1 are also applicable to this embodiment, and will not be repeated here. The system described in this embodiment includes:

The space judging module 201 is used for judging whether the volume of the file to be cached is larger than the current remaining storage space of the device when the device specifies the file to be cached; if the volume of the file to be cached is larger than the remaining storage space, the The difference between the volume of the cache file and the remaining storage space is used as supplementary space.

The screening management module 202 is configured to screen one or more cached cache files as files to be cleaned according to preset screening rules; the volume of the files to be cleaned is not smaller than the supplementary space; and the file to be cleaned is added to list to be cleaned up, and display the list to be cleaned up.

The file cleaning module 203 is configured to, when the device generates a deletion instruction for the list to be cleaned, delete the files to be cleaned in the list to be cleaned according to the deletion instruction.

The file caching module 204 is configured to start caching the specified file to be cached.

From the above technical solutions, it can be seen that the beneficial effects of the system in this embodiment are: using the screening rules, pre-filtering cache files with low demand and appropriate volume for the user as files to be cleaned; Cleanup list guides users to directly operate on the cleanup list to achieve the purpose of cleaning up the storage space; avoids the process of manually searching for the directory to retrieve cached files in the existing storage space cleaning process, and also prevents users from forgetting to clean up the storage space space, or don't know how to clear storage space.
