Once you’ve opened the Prefetch folder, you can delete all files contained within it. Worry not; deleting these files won’t harm your system. To remove the files, simply pick them all by hitting Ctrl + A to select everything, and then press the delete key to clean out the folder. This action should free up some initial space.
Removing Temporary Files
Next, you will repeat the process but this time for the temporary files. Open the Run command again and type temp, then press OK. Follow the same delete process as before—select all files and delete them. If some files cannot be deleted because they are in use, don’t hesitate to try again later when other applications aren’t running.
