Cleaning up a disk involves removing unneeded files to make room for other files on your computer, which can be difficult if you don’t know the significance of each file. You can use a Windows program called Disk Cleanup to clean up your hard disk drive safely and effectively. Disk Cleanup searches your drive, then lists temporary files, Internet cache files, the Recycle Bin, and unnecessary program files that you can safely delete. Disk Cleanup also gives you the option to remove Windows components and installed programs that you no longer use. You can select the types of files you want Disk Cleanup to delete. Before you select and delete files, make sure you will not need them in the future. If you have multiple users on your computer, you can specify whether to clean up only your files or all the files on the computer (New!).
