i have some suggestions:
When you click on a box it will take you to the file so you know what box(s) is what file(s).
Also, when ever i run it it never defrags whole hard drive, it always leaves the big files untouched and unmoved to the out side.(yes i did check off to move to out edge)
And if you could make it so when you press the X or _ you make it go to the system tray, and i order to close it you must right click and do exit program.
Those are just suggestions id like to make becuase they bothered me or i thought would make defraggler a better program.
