Normally defrag programs are only specialized in checking the hard drive of your PC, but this My Defrag doesn`t have this limitation. It can check hard drives, USB sticks, diskettes, etc.
The My Defrag defrag process is very quick and easy, so you can have all these storage devices well optimized, and so make them more efficient in use.
As a curiosity, My Defrag also contains a screensaver which, when it starts running, also starts the hard drive defrag process.
