If you had never thought of yourself as of a space hog, cleaned your e-mail folders on a regular basis, moved pictures and files to DVD and deleted the copies from the hard disk, uninstalled the unnecessary programs as soon as they were no longer needed, and did other things to keep your PC clean and running fast. Have you still wondered why has the computer kept getting slower, and the free room kept shrinking day after day? Have you tried to figure out how can that be stopped? Certainly, buying a faster computer is not an option!
