Auslogics Disk Defrag Screen Saver is an easy-to-use application that will allow you to defragment your disks in Screen Saver mode. Like other screensavers in Windows, defrag screensaver starts automatically when a system has been idle for a few moments. Auslogics Disk Defrag Screen Saver does not require any user interaction during the defragmentation process. It will defragment your disks automatically while you are away from your computer. Once you resume work, defrag screensaver stops immediately and doesn’t start until the next system idle time.
