Use the Command Line for a Quick Cleanup of Windows Temp Files

toggle-button

 The previous tip showed how to configure Windows Disk Cleanup to reduce the time that temp files are kept. A simple approach that allows the deletion of temp files right away uses the Windows command line and the environment variable %TEMP%. Open the command line and enter:

   del /q/f/s %TEMP%\*

One precaution to observe: do not apply this command right after installing updates or new programs that require a reboot. Sometimes these processes use temp files to finish installation.

The files are probably in use or locked by some program. Unless they are taking up a lot of space, they can be probably be left alone.
