Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

Fig. 1 shows a flowchart of a system file detection method according to an embodiment of the present invention. As shown in Figure 1, the method includes the following steps:

Step S100, regularly search the root directory and at least one subdirectory containing system files, calculate the total size of all system files in the root directory as root directory data, and/or the total size of all system files in each subdirectory as subdirectory data, and/or the size of each system file as system file data.

Optionally, a root directory containing system files and at least one subdirectory may be searched through a program that is run regularly, for example, the program is set to run at 22:00 every day.

In the file system of the computer, the root directory refers to the top-level directory of the logical drive, which is relative to the subdirectory; the subdirectory is a directory in the root directory, and there can be subdirectories in the subdirectory, and the subdirectory is There is no limit. Take the file system of the computer as an example to illustrate the root directory and subdirectories, for example: C:\ is the root directory, C:\Windows is the subdirectory of C:\; C:\Windows\System32\ is the subdirectory of C:\Windows Table of contents.

Step S110, storing or updating root directory data and/or subdirectory data and/or system file data in the database.

Since the server is always running, new system files will be continuously generated or original system files will be updated during the running process. Therefore, it is necessary to store or update root directory data and/or subdirectory data and/or system file data in the database.

Step S120, process the data stored in the database according to the viewing command input by the user, and present the processed data in a preset presentation manner.

When the user wants to view root directory data and/or subdirectory data and/or system file data, he can view root directory data and/or subdirectory data and/or system file data by inputting a view command. Before presenting the root directory data and/or subdirectory data and/or system file data to the user, the server processes the data stored in the database, and presents the processed data in a preset presentation manner.

Step S130, cleaning up system files whose size is greater than a first predetermined value or whose data growth rate is greater than a second predetermined value according to the processed data.

According to the processing of data in step S120, the size of the system files is greater than the first predetermined value, such as 2G, or the growth rate of the system file data is greater than the second predetermined value, such as 1G/per day. System files are cleaned, such as moving the system files to an alternative Saved by the server.

Specifically, the settings of the first predetermined value and the second predetermined value are set according to the usage status of the disk, the memory size of the disk, and the operating conditions of the system. For example, the memory size of the disk is 200G, and the disk has been used 50%, then the first predetermined value can be set to 10G, and the second predetermined value can be set to 5G. When the size of a certain system file is larger than 10G, the system file can be cleaned up to prevent the system file from being too large and the system file size larger than 10G. When there are too many files, the storage space of the disk is not enough, which affects the operation of the system and causes the system to crash; when the data growth rate of the system files is greater than 5G/day, it means that the data of the system files may be very large after the growth, and it is possible that the next scheduled Before the time arrives, the disk will not have enough storage space to store the system file due to the rapid growth of the system file, causing the data of the system file to be lost. Cleaning can avoid the above problems. Wherein, those skilled in the art can specifically set the values of the first predetermined value and the second predetermined value according to the needs of practical applications, which are not specifically limited in this embodiment.

From the above description, it can be seen that comparing the above-mentioned processed data with the first predetermined value and the second predetermined value can play a role in guiding which files in the system files to clean up, so as to discover the changes of the system files in time and avoid The resulting system file data loss and system crash issues.

According to the method provided by the above-mentioned embodiments of the present invention, by regularly searching the root directory and at least one subdirectory containing system files, the total size of all system files under the root directory is calculated as root directory data, and/or all system files under each subdirectory as subdirectory data, and/or the size of each system file as system file data; store or update root directory data and/or subdirectory data and/or system file data in the database; view commands entered by the user , process the data stored in the database, and present the processed data in a preset display mode; according to the processed data, the size of the system file is greater than the first predetermined value or the growth rate of the system file data is greater than the second predetermined value System files are cleaned up. After calculating and storing the root directory data and/or subdirectory data and/or system file data, the corresponding data is stored in the database for the later needs of users to view at any time, avoiding the need for temporary calculation when users want to view relevant data defects, and presenting the processed data in a preset presentation mode can intuitively reflect the relationship between system files and data, saving the time for users to view directories one by one, and simplifying the viewing process for users; according to the presentation data, and further clean up the system files whose size is greater than the first predetermined value or the growth rate of the system file data is greater than the second predetermined value, thereby preventing some system files from being too large or suddenly increasing in size resulting in a system crash.

Fig. 2 shows a flowchart of a system file detection method according to another embodiment of the present invention. As shown in Figure 2, the method includes the following steps:

Step S200, periodically search for the root directory and at least one subdirectory containing system files.

In the file system of the computer, the root directory refers to the top-level directory of the logical drive, which is relative to the subdirectory; the subdirectory is a directory in the root directory, and there can be subdirectories in the subdirectory, and the subdirectory is There is no limit. Take the file system of the computer as an example to illustrate the root directory and subdirectories, for example: C:\ is the root directory, C:\Windows is the subdirectory of C:\; C:\Windows\System32\ is the subdirectory of C:\Windows Table of contents.

Specifically, the server can start a program to be run regularly to search, for example, the program can be selected to run at 12 o'clock every night when the system files change slowly, and the root directory and at least one subdirectory containing the system files can be searched through this program.

Step S210, detect whether the MD5 value of the root directory and/or subdirectories and/or system files changes, if it is detected that the MD5 value of the root directory and/or subdirectories and/or system files changes, then perform step S220; if If it is detected that the MD5 value of the root directory and/or subdirectories and/or system files has not changed, step S230 is executed.

Use the hash algorithm to calculate the MD5 value of the root directory and/or subdirectory and/or system file. The MD5 value is calculated based on various comprehensive information of the root directory and/or subdirectory and/or system file at that time, and the root The MD5 value of a directory and/or subdirectory and/or system file is unique, and when the root directory and/or subdirectory and/or system file change, the corresponding MD5 value will also change. The comprehensive information may be the name of the root directory and/or subdirectory and/or system file, modification date, etc., which is not limited in the present invention. Therefore, it can be determined whether the root directory and/or subdirectories and/or system files change by detecting whether the MD5 value of the root directory and/or subdirectories and/or system files changes.

Since the server program will update the system files every day, it will calculate the MD5 value of the root directory and/or subdirectory and/or system file every day, and detect whether the MD5 value of the root directory and/or subdirectory and/or system file has changed mainly By comparing the MD5 calculated on the current day with the MD5 calculated last time, it is judged whether the MD5 values of the two times are the same, if the MD5 values of the same root directory and/or subdirectory and/or system file have not changed, Then the MD5 value of the root directory and/or subdirectories and/or system files changes, and the root directory and/or subdirectories and/or system files change. The method of comparing the MD5 value is used to determine whether the MD5 value has changed, so the MD5 value obtained by each calculation needs to be stored in the database for the next comparison.

Step S220, calculating corresponding root directory data and/or subdirectory data and/or system file data.

Detecting that the MD5 value of the root directory and/or subdirectories and/or system files has changed indicates that the root directory and/or subdirectories and/or system files have changed, and it is necessary to calculate the corresponding root directory data and/or subdirectory data and /or system file data.

Step S230, do not update the corresponding root directory data and/or subdirectory data and/or system file data in the database.

If it is detected that the MD5 value of the root directory and/or subdirectories and/or system files has not changed, indicating that the root directory and/or subdirectories and/or system files have not changed, then the corresponding root directory data and/or subdirectories in the database will not be updated. Directory data and/or system file data are updated.

Step S240, storing or updating root directory data and/or subdirectory data and/or system file data in the database.

Specifically, the following data is stored or updated in the database: the root directory identifier, the root directory data, and the mapping relationship between the root directory identifier and the root directory data;

And/or, each sub-directory identifier, each sub-directory data, and the mapping relationship between the sub-directory identifier and the sub-directory data;

And/or, each system file identifier, each system file data, and the mapping relationship between the system file identifier and the system file data.

Wherein, the identifier may be the name or path of a root directory, a subdirectory, or a system file, which is not limited in the present invention, and those skilled in the art may specifically define the identifier according to actual needs. The mapping relationship between the identifier and the data reflects the corresponding relationship between the identifier and the data. Taking the root directory C:\ as an example, the root directory identifier is the C drive, and the root directory data is 30G. To the data is 30G.

In step S250, according to the viewing command input by the user, the data stored in the database is processed, and the processed data is presented in a preset presentation manner.

Specifically, the following methods can be used to process the data and present the processed data:

Method 1: Extract all the data in the database according to the command input by the user to view all the data in the database, and present the extracted data in a tree structure or a table structure.

In step S240, the root directory data and/or subdirectory data and/or system file data have been stored in the database, so the user can check the corresponding data at any time as needed. When the user inputs a command to view all the data in the database, the server extracts all the data from the database after receiving the view command sent by the user, and presents the extracted data to the user in a tree structure or a table structure.

Method 2: sort the root directory and/or subdirectories and/or system files based on the root directory data and/or subdirectory data and/or system file data according to the command entered by the user to view sorted data, and present the sorted files in sequence data.

In step S240, the root directory data and/or subdirectory data and/or system file data have been stored in the database, so the user can check the corresponding data at any time as required. When the user enters the command to view the sorted data, after receiving the command to view the sorted data from the user, the server first sorts all the data in the database. In the foregoing, after the root directory and/or subdirectories and/or system files are sorted according to the root directory data and/or subdirectory data and/or system file data, the sorted data is presented sequentially.

Method 3: sort the root directory and/or subdirectories and/or system files according to the growth rate of the root directory data and/or subdirectory data and/or system file data according to the command to view the growth rate entered by the user, and present them in order sorted data.

In step S240, the root directory data and/or subdirectory data and/or system file data have been stored in the database, so the user can check the corresponding data at any time as required. When the user inputs a command to check the growth rate, after receiving the command to check the growth rate sent by the user, the server checks the root directory and/or subdirectory data according to the growth rate of the root directory data and/or subdirectory data and/or system file data. Directories and/or system files are sorted, and the sorted data is presented sequentially. Among them, the growth rate reflects the change of data, for example, the data increases from 1G to 10G within one day.

Method 4: compare the root directory data and/or subdirectory data and/or system file data with the set threshold according to the command entered by the user to view data greater than the set threshold, and present the data greater than the set threshold.

In step S240, the root directory data and/or subdirectory data and/or system file data have been stored in the database, so the user can check the corresponding data at any time as required. When the user inputs a command to view data greater than the set threshold, the server will combine the root directory data and/or subdirectory data and/or system file data with the set Compared with the set threshold, the data greater than the set threshold is presented. For example, the user inputs a command to view data larger than 2G, and after receiving the command, the server compares the root directory data and/or subdirectory data and/or system file data with the threshold 2G, and then presents the data larger than 2G.

The above-mentioned methods 1 to 4 have introduced the display methods of data, but the present invention is not limited thereto, and those skilled in the art can set the display methods according to actual needs, which will not be repeated here.

Step S260, cleaning up system files whose size is greater than a first predetermined value or whose data growth rate is greater than a second predetermined value according to the processed data.

According to the processing of data in step S250, the system files whose size is greater than a first predetermined value such as 2G or the growth rate of system file data is greater than a second predetermined value such as 1G/per day are cleaned up, for example, the system files are moved to an alternative Saved by the server.

Specifically, the settings of the first predetermined value and the second predetermined value are set according to the usage status of the disk, the memory size of the disk, and the operating conditions of the system. For example, the memory size of the disk is 200G, and the disk has been used 50%, then the first predetermined value can be set to 10G, and the second predetermined value can be set to 5G. When the size of a certain system file is larger than 10G, the system file can be cleaned up to prevent the system file from being too large and the system file size larger than 10G. When there are too many files, the storage space of the disk is not enough, which affects the operation of the system and causes the system to crash; when the data growth rate of the system files is greater than 5G/day, it means that the data of the system files may be very large after the growth, and it is possible that the next scheduled Before the time arrives, the disk will not have enough storage space to store the system file due to the rapid growth of the system file, causing the data of the system file to be lost. Cleaning can avoid the above problems. Wherein, those skilled in the art can specifically set the values of the first predetermined value and the second predetermined value according to the needs of practical applications, which are not specifically limited in this embodiment.

From the above description, it can be seen that comparing the above-mentioned processed data with the first predetermined value and the second predetermined value can play a role in guiding which files in the system files to clean up, so as to discover the changes of the system files in time and avoid The resulting system file data loss and system crash issues.

According to the method provided by the above-mentioned embodiments of the present invention, by regularly searching the root directory and at least one subdirectory containing the system file, it is detected whether the MD5 value of the root directory and/or the subdirectory and/or the system file changes. , if it is detected that the MD5 value of the root directory and/or the subdirectory and/or the system file changes, then calculate the corresponding root directory data and/or subdirectory data and/or system file data; if detected If the MD5 value of the root directory and/or the subdirectory and/or the system file has not changed, then the corresponding root directory data and/or subdirectory data and/or system file data in the database will not be processed. Update, store or update the root directory data and/or subdirectory data and/or system file data in the database, process the data stored in the database according to the view command input by the user, and present the processed data in a preset presentation mode Data: according to the processed data, system files whose size is greater than a first predetermined value or whose growth rate of system file data is greater than a second predetermined value are cleaned up. By comparing the MD5 value, the calculation task of the server can be reduced. For the root directory and/or subdirectory and/or system files whose data has not changed, the calculation of the corresponding data may not be performed, and the calculation and storage of the root directory data and/or subdirectory data and After / or system file data, store the corresponding data in the database for future users to view at any time, avoiding the defect of temporary calculation when the user wants to view relevant data, and present the processed data in a preset presentation mode The data can intuitively reflect the relationship between system files and data, which saves the time for users to view directories one by one, and simplifies the process of viewing by users; according to the presented data, the size of system files is further determined to be larger than the first predetermined The value or the growth rate of the system file data is greater than the second predetermined value to clean up the system files, thereby preventing the system from crashing due to the excessive size of some system files or the sudden increase in the size of the system files.
