Disk Cleanup helps free up space on your hard drive. Disk Cleanup searches your drive, and then shows you temporary files, Internet cache files, and unnecessary program files that you can safely delete. You can direct Disk Cleanup to delete some or all of those files.

Sometimes Windows uses files for a specific purpose and then retains them in a folder designated for temporary files. Alternatively, you may have previously installed Windows components that you are no longer using. For a variety of reasons, including running out of space on your hard drive, you may want to reduce the number of files on your disk, or create more free space, if it can be done without harming any of your programs.
