i often do a disk cleanup on my windows computer to keep my hard drive running faster. but have you ever wondered if disk cleanup misses other files. the answer is yes, i will show you once folder where disk cleanup does not clean.

its the C:\Users\[USER]\AppData\Local\Temp

NOTE: [USER] is whatever your username is

there you will find some folders that when you try to install some programs, they are extracted and they are left behind. some apps do remove the folders as part of the installation process, but sometimes, when we inturep an installation or the installation itself does not delete these files, they are left behind, so remove all the folders. but dont have to remove the files, only the folders.

Also, when your run disk cleanup, right click on disk cleanup and select 'Run as Administrator' to do a full cleanup
