The main solution of the embodiment of the invention is as follows: in the process of installing or using the application program, when a new directory is detected to be created, the application program name corresponding to the new directory and the path of the new directory are stored in a database, so that the folder directory generated by each application program can be accurately monitored, the residual file corresponding to each application program is collected, and the accuracy of identifying the residual file of the application program is improved; then establishing an incidence relation between the application program and a database corresponding to the application program; after the application program is unloaded, the residual files in the database corresponding to the application program can be cleared according to the association relation without manually searching the residual files of the application program by a user and then clearing the residual files, so that the user experience is improved, the residual files of the mobile terminal are reduced, and the performance of the mobile terminal is improved at the same time.
In the embodiment of the invention, at present, various application programs are installed in the mobile terminal to meet various requirements of a user, when a certain application program is uninstalled, due to the performance of an operating system of the mobile terminal or the installation characteristics of the application program, the condition of incomplete uninstallation often exists, so that residual files are left in the mobile terminal, the residual files accumulate day by day, the storage space of the mobile terminal, such as a memory card, is occupied by the residual files, the resource waste is caused, and the performance is influenced. However, the manual search of the associated residual file by the user requires many user operation steps, and it is generally difficult for a user unskilled in operating the mobile terminal to find the location of the residual file, so that the manual cleaning of the residual file is inconvenient for the user operation.
In the process of installing or using the application program, when a new directory is detected to be created, the application program name corresponding to the new directory and the path of the new directory are stored in a database, so that the folder directory generated by each application program can be accurately monitored, the residual file corresponding to each application program is collected, and the accuracy of identifying the residual file of the application program is improved; then establishing an incidence relation between the application program and a database corresponding to the application program; after the application program is unloaded, the residual files in the database corresponding to the application program can be cleared according to the association relation without manually searching the residual files of the application program by a user and then clearing the residual files, so that the user experience is improved, the residual files of the mobile terminal are reduced, and the performance of the mobile terminal is improved at the same time.
The invention provides a method for clearing residual files.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for removing a residual file according to a first embodiment of the present invention.
In this embodiment, the method includes:
step S10, in the process of installing or using the application program, when detecting that a new directory is created, storing the application program name corresponding to the new directory and the path of the new directory into a database;
in this embodiment, after a certain application is installed in the mobile terminal, in the process of running the application, a folder is generated in the storage space of the mobile terminal, the folder stores data files read and written by the application, and these folders and data files are residual files, for example, a certain music player correspondingly generates a lyric folder and lyric files in the lyric folder in the storage space. At present, when an application is uninstalled, an operating system of a mobile terminal cannot identify which application in a storage space has been created, and thus cannot remove the folders and cannot remove corresponding data files, so that in the process of installing or using the application, when a new directory is detected to be created, an application name corresponding to the new directory and a path of the new directory can be saved in a database, and the application corresponding to the new directory can be identified later.
Step S20, establishing the incidence relation between the application program and the database corresponding to the application program;
in order to achieve the above object, after the application program name corresponding to the new directory and the path of the new directory are saved in the database, an association relationship between the application program of the new directory and the database corresponding to the application program needs to be established, so as to search for a residual file of the application program in the following.
And step S30, after the application program is uninstalled, clearing the residual file in the database corresponding to the application program according to the incidence relation.
After the incidence relation between the application program and the database corresponding to the application program is established, the application program can be monitored in real time or at regular time, if the situation that the application program is unloaded is monitored, the residual files in the database corresponding to the application program are removed according to the incidence relation after the application program is unloaded. Specifically, after the application program is uninstalled, the residual file of the application program can be directly searched according to the association relationship, and then the residual file is cleaned.
In the method for removing the residual file provided by the embodiment, in the process of installing or using the application program, when it is detected that a new directory is created, the application program name corresponding to the new directory and the path of the new directory are stored in the database, so that the folder directory generated by each application program can be accurately monitored, the residual file corresponding to each application program is collected, and the accuracy of identifying the residual file of the application program is improved; then establishing an incidence relation between the application program and a database corresponding to the application program; after the application program is unloaded, the residual files in the database corresponding to the application program can be cleared according to the association relation without manually searching the residual files of the application program by a user and then clearing the residual files, so that the user experience is improved, the residual files of the mobile terminal are reduced, and the performance of the mobile terminal is improved at the same time.
Further, referring to fig. 2, a second embodiment of the method for clearing residual files according to the present invention is proposed based on the first embodiment of the method for clearing residual files according to the present invention.
In this embodiment, the step S20 is further followed by:
step S40, inquiring the residual file of the application program through the directory path associated with the unloaded application program name in the database;
and step S50, clearing the inquired residual file and updating the data in the database.
In this embodiment, after the application program is uninstalled, the residual file of the application program may be automatically queried through the directory path associated with the name of the uninstalled application program in the database, and then the queried residual file is cleared and the data in the database is updated, so as to reduce the residual file in the database, or the user may manually query the residual file of the application program through the directory path associated with the name of the uninstalled application program in the database, which is not limited herein.
In the method for removing a residual file provided in this embodiment, a directory path associated with an uninstalled application name in a database is used to query the residual file of the application; and clearing the inquired residual files and updating the data in the database, so that the residual files of the mobile terminal are reduced, and the performance of the mobile terminal is improved.
Further, referring to fig. 3, a third embodiment of the method for clearing residual files according to the present invention is proposed based on the first embodiment of the method for clearing residual files according to the present invention.
In this embodiment, the step S20 includes:
step S21, obtaining the number of application programs accessing the database;
step S22, judging whether the number of the application programs accessing the database is less than a preset threshold value;
step S23, if the number of the application programs accessing the database is smaller than a preset value, establishing an association relationship between the application programs and the database corresponding to the application programs.
In this embodiment, before establishing an association relationship between an application program and a folder corresponding to the application program, first, the number of application programs accessing the database needs to be obtained, and then, whether the number of application programs accessing the database is smaller than a preset threshold value is judged; the preset threshold value can be 2, that is, when it is monitored that two or more processes of the application program access the same database, the database is a public database, and a file in the database cannot be used as a residual file; if the database is read and written by only one application program process after long-term monitoring, the database is only corresponding to the name of the application program, and therefore, when the number of the application programs accessing the database is smaller than a preset value, the incidence relation between the application programs and the database corresponding to the application programs is established.
In the method for removing the residual file provided by this embodiment, the number of the application programs accessing the database is obtained; then judging whether the number of the application programs accessing the database is smaller than a preset threshold value or not; if the number of the application programs accessing the database is smaller than a preset value, establishing an incidence relation between the application programs and the database corresponding to the application programs, so that the public database is prevented from being deleted, and the accuracy of cleaning the residual file is further improved.
Further, referring to fig. 4, a fourth embodiment of the method for clearing residual files according to the present invention is proposed based on the first embodiment of the method for clearing residual files according to the present invention.
In this embodiment, the step S30 includes:
step S31, acquiring a database corresponding to the application program according to the incidence relation, and acquiring the type of the residual file in the database;
step S32, judging whether the type of the residual file meets the preset condition;
step S33, if the residual file meets the preset condition, the residual file is cleared;
step S34, if the residual file does not satisfy the preset condition, retaining the residual file.
In the embodiment, before the residual file is cleaned, in order to improve the experience of a user in using the mobile terminal, firstly, a database corresponding to the application program is obtained according to the incidence relation, the type of the residual file in the database is obtained, and then whether the type of the residual file meets a preset condition is judged; and if the residual file does not meet the preset condition, reserving the residual file. Specifically, the preset condition may be a residual file and not a file currently used by the operating system. In particular, the file currently used by the operating system may be a ring tone file, a wallpaper file, and the like. For example, if the type of the residual file is in jpg (JPEG, Joint Photographic Experts GROUP) format and the file name is desktop wallpaper, it indicates that although the file is a residual file, the file is not suitable for deletion, and if deleted, the desktop wallpaper may be rendered unusable; therefore, such files do not act as a residual file for the application in order to avoid affecting the user's use. It is understood that the corresponding file type may also be set as the preset condition according to other situations, and the above example is only illustrative and is not limited herein.
According to the method for clearing the residual file, before the residual file is cleared, the database corresponding to the application program is firstly obtained according to the incidence relation, the type of the residual file in the database is obtained, whether the type of the residual file meets the preset condition or not is judged, if the residual file meets the preset condition, the residual file is cleared, otherwise, the residual file is reserved, the phenomenon that a user cannot use the residual file after deleting the specific type of file is avoided, and therefore the experience of the user in using the mobile terminal is improved.
Further, referring to fig. 5, a fifth embodiment of the method for clearing residual files according to the present invention is proposed based on the first embodiment of the method for clearing residual files according to the present invention.
In this embodiment, the method further includes:
step S60, calculating the size of the directory file associated with each application program in the database;
step S70, sorting the sizes of the directory files obtained by calculation to obtain a size sorting table of the directory files;
step S80, selecting the directory file pushed to the user according to the size sorting table of the directory file, and pushing the selected directory file and the corresponding application program to the user;
and step S90, cleaning the corresponding application program according to the received cleaning instruction.
In this embodiment, the application program name corresponding to the new directory and the path of the new directory are saved in the database; after the incidence relation between the application program and the database corresponding to the application program is established, the size of a directory file associated with each application program in the database can be calculated in real time or at regular time in the process that a user uses the application program; then sorting the sizes of the directory files obtained by calculation to obtain a directory file size sorting table; selecting directory files pushed to a user according to the directory file size sorting table, specifically, the sorting method can be descending sorting or ascending sorting, when the sorting method is descending sorting, the first ten directories in the directory file size sorting table can be selected as the directory files pushed to the user, application programs corresponding to the first ten directory files are extracted, and the selected directory files and the corresponding application programs are pushed to the user; the user can know which application programs occupy more storage space conveniently, and further, in the pushing process, important folder names contained in the pushed application programs can be further pushed to the user, so that the user is reminded to clean up carefully; and when a cleaning instruction sent by a user is received, cleaning the corresponding application program according to the received cleaning instruction.
In the method for removing the residual file provided by this embodiment, the size of the directory file associated with each application program in the database is calculated; sorting the sizes of the directory files obtained by calculation to obtain a size sorting table of the directory files; then, selecting a directory file to be pushed to a user according to the size sorting table of the directory files, and pushing the selected directory file and a corresponding application program to the user; when the cleaning instruction is received, the corresponding application program is cleaned according to the received cleaning instruction, so that the user can conveniently perform slimming cleaning on the application program, the user experience is improved, and the performance of the mobile terminal is improved.
