How do automatically defrag my hard-drive?

Disk Booster can automatically schedule a defragmentation of your hard-disks when your PC is idle. To use this feature, select Autodefrag and then select I want to use Autodefrag and let Disk Booster automatically optimize my computer when it’s idle. You can also choose when the auto-defrag process should begin after your computer becomes idle.

If you are leaving your PC for coffee when working in between documents, you may want to increase this period before disk defrag begins. If you want it to start immediately, just enter 0 in the edit field here. You can also specify which drives need to be defragmented by clicking their appropriate checkbox from the options presented there.
