How to Clear Hard Drive Space in Windows 7

To start clearing away at some of the unwanted files currently on your hard drive, you don't need to look any farther than Windows 7’s Disk Cleanup tool. For a built-in feature, Disk Cleanup is simple and powerful program for freeing up of unnecessary files. It removes temporary files, empties the Recycle Bin, and removes a variety of system files and other items that you no longer need. Depending on how often you run Disk Cleanup, this operation can regain a lot of disk space for you.

1. Open Disk Cleanup by clicking the Start button , clicking All Programs, clicking Accessories, clicking System Tools, and then clicking Disk Cleanup.
2. In the Disk Cleanup Options dialog box, choose whether you want to clean up your own files only or all of the files on the computer.  If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
3. If the Disk Cleanup: Drive Selection dialog box appears, select the hard disk drive that you want to clean up, and then click OK.
4. Click the Disk Cleanup tab, and then select the check boxes for the files you want to delete.
5. When you finish selecting the files you want to delete, click OK, and then click Delete files to confirm the operation. Disk Cleanup proceeds to remove all unnecessary files from your computer.
