Normal, everyday usage of your computer causes files on the hard drive to become fragmented, which usually results in reduced performance. To alleviate this problem, Microsoft suggests that Windows computers be defragmented periodically. Unfortunately, most users forget or neglect to perform this necessary function. The Defrag Timer program can help you maintain optimum system performance and stability by automatically performing disk defrags on a schedule that you determine. And the best part is that this critical task can be performed quietly, almost unnoticed in the background, while you're surfing on the Internet, playing games, or balancing your checkbook. Other products such as Diskeeper do the same thing, but at a much higher price.
