Hey, I've read that I can't really Lose or Gain space when Defragging. Can you help explain to me why I lost over 6GB first time defrag and gained over 21GB for the second defrag? Thanks in advance

I just continued my run of Defraggler to defrag my C drive. And now instead of decreasing free space I'm gaining Free space of the defrag process goes on. It seems that I needed to Check Disks before anything. Edit: My bad, it did inscrease at first but after 38% of defrag the Free memory space got reduced again!! no!. Good thing I know the solution haha. Update: My final Free space after Defrag is now 69.6GB (from the original 48gb) I gained over 21GB!!!

SOLUTION!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Guys I was searching around and i found this forum [http://forum.piriform.com/index.php?showtopic=16464&st=0&gopid=121877entry121877] This is what I posted on that forum in response to the success of the solution posed: I also Ran Defraggler again and now instead of reducing disk space during the process I gain! So i can conclude that The Check Disk thing is what's needed to be done before anything in Defraggler. Hope this helps most of you out there .

THANK!!!! I ran Defraggler and after around an hour I noticed I lost 6.1GB (from 48gb free to 41.9!)!!! and it was only 30% done! So I Immediately stopped Defragmentation and searched online about it. It seemed that it has been happening to alot of people and the most common explanation was "System Restore Points", some suggested me to run a disk cleanup and after elaborating the search on that I found that the Built in Disk Cleanup (in vista) would >>>>DELETE ALL things on a hrad drive<<<< (due to some registry problem). Anyways I left that alone. [use CCleaner instead!! haha] Then I found this post and I tried the thing where in Defragger click 'Action' (in top left) > 'Advance' > 'Check drive for errors' and to my relief I gained all my GBs back after 'Verifying Drive'!!! yay!!! Not only did I gain it back, i got an additional 1.6GB!!!! So from 48GB Free, I ran Defraggler ...... after 30%defrag it became 41.9GB....stopped it.... ran dive check.... now have 49.6GB free.
