What am I doing wrong with "Defrag Free Space"

I don't understand why "Defrag Free Space" seems to work so poorly.  I am defragging a 2-TB drive, Windows 7 Pro SP1, with 21 percent free space.  After finishing the free space defrag (NOT the "allow fragmentation" version), I end up with many dozens of free space gaps, some quite large relatively speaking, and one very large free space at the end.

 

I don't understand why all the free space gaps.  I mean, how hard can it be to start at the beginning of the drive, move things up and left to fill in free spaces, and continue to the end?  I understand that some things can not be moved, so I can understand and live with a few (two or three or up to a half dozen) small gaps where there are no files small enough to fill in.  But if I were to count them I'm sure I would count well in excess of a hundred free space gaps, some of which are several blocks long on the drive map display (don't know how big one drive map block is but a VERY rough estimate is 9000 blocks shown on the display, divided into 2 terabytes disk size, equals roughly 200 megabytes per block on the screen).  I have one of those that is 17 display blocks long, meaning roughly 3.4 gigabytes of free space.  Defraggler couldn't find a file small enough to put in that space??  It couldn't just move things up and left to fill in that space and most other large spaces to leave a larger contiguous free space?

 

Note that I am not using "Defrag free space (allow fragmentation)" because I don't want to re-fragment the files I just defragged.  Anyway, as I said it shouldn't be needed as I would think the defragger could just move things up and left to fill in most of the blanks.

 

What am I doing wrong here?  This can't be right.

Good afternoon, eL_PuSHeR.

 

Yes, it does seem buggy, which is puzzling since I would think that defragging free space would be among the easiest of all tasks that a defragger is called upon to do.

 

Not meaning to redirect anyone away from Defraggler, I like Defraggler in other ares and plan to continue to use (and support) it, but is there another defragger out there that will do a decent job of defragging free space without re-fragmenting a long list of files in the process?

 

I don't even care if it takes a while, happy to just let it run all weekend if need be, but is there something out there that will just move files left and up to fill in free space, and continue to do that from beginning to end?

 

Thanks...

Of course, I did extensively "google for them" and was not able to find a deterministic answer, hence here... sorry, I thought by now that went without saying.  There are lots of defraggers, some of which claim to defrag free space, but of course no way of knowing for certain other than downloading and installing each and every one of them and trying it... or, asking the good folks on this forum, some of whom might have the answer at the tips of their fingers.
