Disk Accelerator Pro is a total defragmentation tool that restores your hard disk to its maximum possible performance. As your disk stores new files, it fragments them -- leading to extremely long load times, slower overall performance, even random crashes and freezes. Once you have Disk Accelerator Pro, you"ll see significant performance increases right away. BONUS! FILE RESTORE DELUXE -- This easy-to-use utility can be a lifesaver. Find and restore lost files with the click of a button. It even restores the original file name and directory structure as though nothing had been deleted in the first place.
