To launch this disk cleanup tool :
1. Click on the Windows orb and type “disk cleanup”, click the first option that shows up.
2. Select the disk partition which needs to be clean up and click Ok.
3. Wait for a while while the tool calculates how much space can be freed up and which files can be removed. For seeing which files will be deleted, select the appropriate ones and click on “View Files”.
