Most of the time, these temporary files never get removed when they are no longer required, and just sit around accumulating over time. One of the common locations that gets used is the TEMP folder which becomes a bit of a junkyard where all programs that require a temporary area to do something, will put their files in there. If you install a program, browse the internet or even just use a program, very often temporary files are being created to allow the applications to function normally. Although most PC users don’t realize it, your computer is constantly filling itself up with junk and useless files in the background.
