This is the software publisher's description.

You probably have better things to do than worry about whether the hard disks on your Windows computer are getting fragmented. Just install Ashampoo Magical Defrag 2. This radically improved program keeps all your computer’s hard disks defragmented, permanently.

Just install it and forget it. Your hard disks will never get fragmented again. And Ashampoo Magical Defrag 2 does this without slowing down your computer or interfering with your work.

The way Ashampoo Magical Defrag 2 works is similar to a screensaver. Whenever the computer is idle the program cuts in automatically and starts cleaning up your hard disk.

It’s like having a robot servant to tidy your home for you whenever you go out. As soon as you start using the computer again the program stops immediately and lets you get on with your work without any interference.
