Computers can slow down over time, and disk fragmentation is generally one of the causes. Fragmented files are broken up and stored on various parts of your disk causing slowdowns, crashes, and slow boot times. The new Diskeeper 10 keeps your PC running as fast as it did when it was new. You'll have no more time-consuming manual defragmentation jobs. Just install Diskeeper 10, then set it and forget it. The program also uses a high-speed defragmentation engine that runs unnoticed in the background, eliminating fragmentation while you use your PC.
