For some friends who like to clear the system garbage, should have tried manually to clean up the junk files in the system? So have you ever encountered a folder that cannot be deleted? Of course, if there is a file inside Folders, we can not delete it is normal, but if some empty folders can not be deleted, do you think it is a bit strange? Below, Xiaobian will take win7 pure version as an example, for everyone to talk about specific the solution now!

a reason the first case leads to an empty folder can not be deleted, for example, Office, WPS series software Office, WPS illegal closure caused, sometimes, when we operate these software programs They will be shut down under abnormal conditions. At this time, there will be a malfunction, and the solution is simple. Run these programs again and then close them normally.
Second, the second case, the image of the file or the DLL dynamic link library called by the program is not released in the memory, there will be a phenomenon that the file is being used and cannot be deleted. Solution: We can delete the operation directly in the DOS environment.
Third, the third situation is the disk error, if there is a disk error, we need to use a professional tool to scan the disk, then we delete the file again.
