Disk Cleanup Wizard
Windows 98, Me, 2000, and XP come with a Disk Cleanup Wizard that streamlines the process of clearing out unwanted temp files. First close all running programs. Then access the Wizard, by clicking on the Start button and choosing Programs (All Programs in Windows XP). Go on to choose Accessories, System Tools, and Disk Cleanup. (A shortcut is to click on Start, choose Run, and type in cleanmgr.)
The wizard will give you the option of cleaning up all your hard drive partitions, if you have more than one. It will show you how much space is being consumed by unneeded temporary Internet files, as well as other temporary files, downloaded program files, and offline Web pages. This Disk Cleanup Helper will even empty the Recycle Bin for you. Just check the box in front of the item, click OK, and the wizard will clean up your disk. Get rid of at least the temporary Internet files and other temporary files. Remember that the files in the Recycle Bin take up hard drive space, so you may want to have the wizard empty your trash as well.
