How to delete files in the operating system on a regular basis? 20

Clean up useless DLL files in the system directory.

This maintenance may not be familiar to you, but it's also a crucial factor in how quickly your system can run. We know that after the application is installed in Windows, it usually copies some DLL files in the System folder under the installation path of Windows. And when you delete the corresponding application, some of the dll files in it are usually retained; When the number of DLL files in this path is increasing, it will greatly affect the overall running speed of the system.

For ordinary users, it is very difficult to manually delete DLL files.

In view of this situation, it is recommended to use the Clean System automatic DLL file scanning and deletion tool, the **** of this tool is that you just need to select the drive available for scanning in the program interface, and click on the interface"start scanning"button, the program will automatically analyze the association between the files in the corresponding disk and the dll files under the system path, and then give a list of dll files that are not associated with all files, at this time you can click the ok button in the interface to delete and automatically backup. I have used it to safely delete 7M dll files without causing any application errors in the system, and the results are very good. 5. Use anti-system crash tools to maintain system stability.

This is another way to maintain your system, which you can use to maintain the stability of your system when you are experiencing instability and you don't know the cause of the problem and don't want to reinstall Windows. This approach protects your application at critical moments, saves data that is staged in system memory to disk, and is often useful when you're about to finish a design or create a piece of art. At present, there are more tools in this area, and after comparison, I think that CrushGuard provided by Norton does a good job in application crash recovery.

It provides rich functions, simple operation mode, high degree of automation, good recovery effect, especially the program can automatically monitor the application that the system is currently running, and then when the crash phenomenon is automatically started, the user only needs to click the anti-freeze button in the mouse dialog box to resume the application, it is very simple to use, and it is recommended that you choose to use it. In addition, there is also a tool that is the Bomb Shelter in Nut Bolts, which is also a good anti-app freeze tool. The feature of this tool is that it is very small, and its recovery results are also good.

You want to use a combination of Windows scheduled tasks and batch processing.

echo Note: For example, if you want to delete the C: 123 A folder, please modify the folder path here as needed, and then clear the ** site.

rd /s /q c:\123\a

attrib -h -s -r "c:\recycler\s-1-5-21-1343024091-57989841-1417001333-500"

rd/s/q "c:\recycler\s-1-5-21-1343024091-57989841-1417001333-500"
