All the above-mentioned optional technical solutions can be combined arbitrarily to form the optional embodiments of the present invention, and are not described herein again.
An embodiment of the present invention provides a method for identifying a file directory, and referring to fig. 2, a flow of the method provided by the embodiment of the present invention includes:
201. in the running process of an application program, when a file directory creation event is monitored, a terminal calls a hook function.
In this embodiment, the terminal may be a smart phone, a tablet computer, a notebook computer, a desktop computer, or the like, and the product type of the terminal is not specifically limited in this embodiment. In order to meet the use requirements of users, a plurality of application programs are installed in the terminal, including an audio and video application program, a navigation application program, a shopping application program, a reading application program, a management application program and the like. The management application is responsible for monitoring the operating system and managing other applications, for example, the management application can clean up junk files generated in the running process of other applications, repair system bugs, check and kill viruses, and the like.
Most application programs need to cache some files, such as pictures, audio, video and the like, in a local storage of the terminal, such as an SD card, in the running process, when a user needs the files again, the terminal preferentially obtains the files from the local storage without pulling the files from the Internet, so that the flow can be saved, and the response speed can be increased. Before caching files for the application program, the terminal needs to create a file directory for the application program on the SD card, and then stores the files needing to be cached in the file directory. With the increase of files cached on the SD card, the usable space on the SD card becomes smaller and smaller, and at this time, the file directory on the SD card needs to be identified, and then the files in the file directory are deleted in a targeted manner, so as to vacate more usable space for the terminal, thereby improving the operation performance of the terminal. Therefore, the method provided by the embodiment monitors the creation event of the file directory in real time in the running process of the application program, calls the hook function when the creation event of the file directory is monitored, and monitors the system function called when the file directory is created for the application program through the hook function.
The hook function is also called a hook function, and is a part of a windows message processing mechanism, and by setting the hook function, an application program can filter all messages and events on the level of an operating system and access messages which cannot be accessed under normal conditions. The hook function is written by a developer as a piece of code to process operating system messages.
During the running process of the application program, when a creation event of a file directory is monitored, the terminal calls a hook function, including but not limited to the following two ways.
In an embodiment of the invention, the terminal acquires the hook function, loads the hook function into the process of the application program in a code injection mode, and then executes the hook function in the process of the application program. In the computer field, code injection is a way to load executable code into an application process.
Under the linux system, the file executable by the terminal operating system is typically a so file, and therefore, in order to enable the hook function injected into the application program process to be executed, the terminal may convert the hook function into the so file before injecting the hook function into the application program process. Wherein the so files are all called Shared objects and are dynamic link library files under the linux system.
In another embodiment of the invention, the terminal can directly call the hook function from the operating system, and the hook function is written into the operating system by modifying the system source code by a manufacturer before the terminal leaves the factory.
202. And the terminal monitors the system function called in the file directory creation process through a hook function.
In this embodiment, when a creation event of a file directory is monitored, the terminal calls a hook function, and monitors a system function called by an operating system when a creation operation of the file directory of an application program is monitored by calling the hook function. The system function is a function inherent in the operating system.
203. And the terminal acquires the attribute information of the file directory according to the system function.
In the technical field of computers, since called system functions are different in the process of creating file directories of different application programs, a terminal monitors the system functions called by an operating system by calling a hook function, and can acquire attribute information of the file directories of the application programs, wherein the attribute information of the file directories is used for indicating the affiliated relationship between the file directories and the application programs, and the terminal can automatically identify the operating system corresponding to each file directory based on the attribute information of the file directories. The attribute information of the file directory includes a file directory name, an application identifier, a creating path of the file directory, and the like, and the embodiment does not specifically limit the attribute information of the file directory.
The attribute information of the file directory is actually acquired by the management application via the terminal.
204. And the terminal reports the attribute information of the file directory to the server.
In order to facilitate management of the attribute information of the file directories of different application programs, after acquiring the attribute information of the file directories, the management application program in the terminal can report the acquired attribute information of the file directories to a server corresponding to the management application program through a network or the like. When the terminal reports specifically, the attribute information of the file directory acquired within the preset time can be reported to the server every other preset time; the obtained attribute information of the file directory can be reported to the server in real time, and the embodiment does not specifically limit the way in which the terminal reports the attribute information of the file directory to the server.
In fact, in addition to the terminal according to the embodiment of the present invention reporting the attribute information of the file directory to the server, other terminals installed with the management application program also report the acquired attribute information of the file directory to the server.
205. And the server processes the attribute information of the file directories reported by the terminals to obtain a junk file list and sends the junk file list to the terminals.
After receiving the attribute information of the file directories reported by the terminals, the server analyzes the received attribute information of the file directories, removes the repeated attribute information of the file directories, and integrates the attribute information of different file directories into a junk file list.
Taking an example that a terminal a, a terminal B, a terminal C, and a terminal D report attribute information of a file directory to a server, where the attribute information of the file directory reported by the terminal a to the server includes attribute information of a file directory one and attribute information of a file directory two, the attribute information of the file directory reported by the terminal B to the server includes attribute information of a file directory three, attribute information of a file directory four, and attribute information of a file directory five, the attribute information of the file directory reported by the terminal C to the server includes attribute information of a file directory two, attribute information of a file directory four, and attribute information of a file directory six, and the attribute information of the file directory reported by the terminal D to the server includes attribute information of a file directory three and attribute information of a file directory seven. The server analyzes the received attribute information of the multiple file directories according to the attribute information of the file directories reported by the terminal A, the terminal B, the terminal C and the terminal D, removes the repeated attribute information of the file directory II, the repeated attribute information of the file directory III and the repeated attribute information of the file directory IV, and obtains a junk file list, wherein the junk file list comprises the attribute information of the file directory I, the attribute information of the file directory II, the attribute information of the file directory III, the attribute information of the file directory IV, the attribute information of the file directory V, the attribute information of the file directory VI and the attribute information of the file directory VII.
For the storage form of the attribute information of the file directory in the garbage file list, see table 1 below.
TABLE 1
| Name of file directory | Application identification | Storage location |
| abcd | 1 | SD card |
| cedg | 2 | SD card |
| wetr | 3 | SD card |
And after the junk file list is obtained, the server sends the obtained junk file list to each terminal provided with the management application program, and each terminal stores the junk file list.
Fig. 3 is a schematic diagram of a process of creating a junk file list, referring to fig. 3, after acquiring attribute information of a file directory, a terminal a, a terminal B, and a terminal C report the acquired attribute information of the file directory to a server, the server receives the attribute information of the file directory reported by the terminal a, the terminal B, and the terminal C, analyzes the received attribute information of a plurality of file directories to obtain a junk file list, and then sends the obtained junk file list to the terminal a, the terminal B, the terminal C, the terminal D, the terminal E, and the terminal F, which are equipped with a management application, and the terminal a, the terminal B, the terminal C, the terminal D, the terminal E, and the terminal F store the junk file list.
206. And when receiving the junk file list sent by the server, the terminal cleans the files in the junk file list according to the junk file list.
In this embodiment, the management application has a garbage cleaning function, based on which, when the management application scans files within the operating system through the terminal, the junk file directory may be identified from the junk file list and after scanning is complete, a junk file processing page may be displayed, see figure 4, the junk file processing page is displayed with junk file directories, each junk file directory is displayed with whether to select options or not, such as "screenshot directory", "junk file directory", "excess installation package directory", "background software directory" in fig. 4, and junk file cleanup options, such as "one-click cleanup acceleration" in fig. 4, and when the garbage file cleaning option is detected to be selected, deleting the files in the selected garbage file directory, thereby vacating more use space for the terminal and improving the performance of the terminal.
Fig. 5 is a schematic diagram of a terminal display interface, referring to fig. 5, when the terminal identifies a junk file directory during full-disk scanning of system files according to a junk file list, the terminal displays a "system album thumbnail", "fragmented files", "cleanable logs", "log logs", "shareSDK advertisements", "first video application advertisements", "second video advertisements", and the like of the identified junk file directory on a junk file processing page, and displays a "one-key cleaning acceleration" option, and when it is detected that the "one-key cleaning option" is selected, a file under the selected junk file directory is deleted.
According to the method provided by the embodiment of the invention, the system function called when the file directory is created for the application program is monitored by calling the hook function, and the attribute information of the file directory is acquired according to the called system function. Because the attribute information of the file directory indicates the affiliation relationship between the file directory and the application program, the application program to which the file directory belongs can be identified without manual identification by a user, so that the identification cost is saved, and the identification precision is high.
Referring to fig. 6, an embodiment of the present invention provides an apparatus for identifying a file directory, where the apparatus includes:
