If so, it's to do with Vista's Volume Shadow Copy and System Restore, and there's an attempt at an explanation here using examples from the web and previous Defraggler topics on the subject.

Vista by default reserves 15% of disk space for defragging.
As Volume Shadow Copy takes up more and more space as you defrag, or do other stuff that makes Vista track changes to files, then to retain that 15% Vista starts to delete System Restore points. This is probably why you don't have any.
So you have the situation it seems where your available free space can seem to disappear, and along with it, as the process continues, your System Restore Points.
Again, I don't have Vista, so can't physically check this process, but the only way it seems to get back your free space, is to delete Volume Shadow Copies.
And maybe we can get some input from Vista users on here who have practical experience of this, and could possibly give you clearer instructions on the "how to".
If you still have worries, or need more advice, don't hesitate to post back and say so. You're not alone with this problem, and your not alone in having concerns over it.
i ran the full defraggles and now it says i have 22.5gb of used space
WHY IS THIS
I HAVE NO SYSTEM RESTORE POINTS
WHAT SHALL I DO ??/
IS THIS PROGRAM FAULTY OR AM I DOING SOMETHING WRONG ????
CAN U PLEZ HELP ME
THANK YOU
Maybe a "stupid" question but don't you have a 40 GB hard drive wich has now 17,5GB of used space and 22,5GB of unused space? (The 0,5 GB extra could have been freed from the defragging)
Is it a desirable thing to do? That's the debatable point. If your free space is disappearing, I believe this is probably the only way to gain it back.
Be aware that deleting Shadow copies also deletes Restore Points, but you don't have to delete them all. See how many you have listed, and maybe delete all but the most recent one or two.
With System Restore, you don't IMHO want to go back too far anyway.
I'll also add that I don't have Vista, and this information is based upon research and many previous topics on this and other forums.
