How to clean up useless things in win7c disk

1. Enter the C drive and clean up useless folders

In the C drive, there are only three folders after installing the system: Documents and

Settings, WINDOWS, and ProgramFiles, as long as they are not in these three folders, you can delete them. If you are not afraid that the software you installed will not be usable, you can directly use the shred file if you encounter problems that cannot be deleted. deal with.

2. Clean Documents and Settings files

Generally, this file contains some configurations of our system. If deleted, only some functions cannot be used. But I personally don’t recommend cleaning it. If you really want to clean it up, just clean up the desktop, because all your desktop files will be stored in this folder. If you encounter a file on your desktop on another disk or delete the file, it will become smaller

3. It is not recommended that you clean up the WINDOWS file, because many of the files inside are files that implement system functions. Deleting the files inside is likely to cause the system to be unable to open, which is what the questioner said cannot be deleted. The files are basically all in this folder.

4. Clean up ProgramFiles

If we install software in the system, the default path of the software is stored in this file. To enter this file, you only need to copy the file name to Soso, and you will know what software the file name corresponds to, so that you can decide whether to delete it according to your own situation. My personal suggestion is to delete them all and then install them again. This time remember to set the path to another disk. In this way, the C drive space will not become larger and larger.
