I understand that Windows XP requires at least 15% free on the drive to defragment using the defragmenter that comes with it. Does Defraggler have any similar constraints and if so what are they?
Depends on what kind of defragmentation Defraggler must do. If you want to defragment the entire disk then more free space the better. If you only want to defragment the fragmented files then Defraggler needs less free space.
Thanks for clarifying.

If not mistaken Defraggler needs at least 10% free space for optimal defrag.
Excessive defragmentation is not recommended - because it will shorten the life of hard drives...
