What is a disk clean up what does it do?

Answer 1

In Windows, a disk clean up is a program in your computer that checks your files for old, out of date things that can be removed such as unused file extensions, websites you may have saved to work offline, your recycle bin, or caches -- which is all the images and texts your computer stores whenever you visit a new website so it loads more quickly the next time.  All this can add up to a surprising amount of space on your computer, so regularly running a disk clean up can free up a ton of space if you do a lot of surfing.
