Strengths: The best drefragger. Defrags almost everything including very large files. Defrags in modes quick and regular. When you use the quick mode or file mode the program just defrags the files when you use the regular mode it defrags the free space as well sometimes it takes a long time especially if there's lots of data or less than 15% free. This program works on XP, Vista and 7 both 32bit and 64 bit. I have used it on all of the above. I friend of mine always drefragged his XP machine with the built in drefragger and was conplaning about how slow his machine had become he couldn't beleive his machine showed over 95% fragmintation I installed and ran this program, CCleaner, and Auslogistics registry cleaning and it ran like a new machine. In my opinion this is the only defragger to use it's better than anyting else out there you can't even pay for better.
Weaknesses: Can be a bit slow.
Overall Evaluation: The best defragger out there.

Strengths: Fast, small download file, good clean up
Weaknesses: Although it seems to do a good job after many months of using I found in fact windows does a better job. I started to notice things were slowing down and my games were taking longer to load. After defragging with windows things improved drastically. I don't think defraggler does a good job of keeping files together but rather seems to just crunch the space
Overall Evaluation: After well over a year I have stopped using the program for defrag. The disk clean up is handy but I think there are better defrag programs out there

Strengths: Nice interface
Weaknesses: Under Win 7, every time I run this program, even in the same session, it will add a minimum of 200MB to the space used. So it seems to have some problem with cleaning up behind itself.
Overall Evaluation: If it did not chew up my disk space it would be very nice. I don't expect to have it installed for long...

Strengths: Nice interface & options
Weaknesses: None so far
Overall Evaluation: I played with Defraggler some more and found that the reason it was running so slow was because I had another automatic defragger running in the background. Kind of slowed things down a bit. After killing the background defragger, Defraggler went about it's business doing what it was supposed to do. I gave it a rating of superior this time, to offset the "fair" rating I gave on my first review, otherwise I'd rate it as very good....

Strengths: Much faster than Windows Defragging tool, free, lets you select specific files to defrag
Weaknesses: None
Overall Evaluation: This is a tool far better than Windows own tools for disk defragging, and far faster. I highly recommend it!

Strengths: I use this on a work system running Windows XP, and it does fine. No speed demon, but it gets the job done in a moderate amount of time. I typically run it over lunch on my personal laptop, and it does fine. Other than a Yahoo Toolbar offer at the front end, no other gotchas that I've found.
Weaknesses: Wish it was a little faster, although with repeat use it does ok
Overall Evaluation: A lot better (and cheaper) alternative to the other suite programs out there.

Overall Evaluation: May be Vista 64 issue but obviously not working correctly.

Strengths: Far better than Windows defrag. Good array of reports and options on how and what to defrag.
Weaknesses: Graphic display of disk sector activity is quite inferior to PC Magazine's free Defrag-a-File which is scalable. Furthermore, the color legend doesn't show all the possible colors. Defraggler also shows a deceptively high figure for fragmented percentage. Its first run, done after using D-a-F, took more than 30 minutes and brought almost no improvement. Subsequent runs only took a few minutes. It does appear to bring a slight increase in used disk space and some of the file size numbers don't quite agree with D-a-F but neither is a significant problem.
Overall Evaluation: Very useful but not quite as good as Defrag-a-File. It showed my disk frag level as 29% as opposed to a more informative 8.5% on D-a-F because Defraggler apparently divides the size of the fragmented files only by the used space on the disk while D-a-F divides it by the total disk capacity. To see why Defraggler's method is deceptive, on a 100 mb drive suppose you had ony two 1 mb files, each fragmented into two parts. Defraggler would report fragmentation as 100% which makes it look like your entire drive space is totally fragmented. D-a-F would show 2% which is more reflective of the state of the entire drive. And the graphic display of the little sector squares really does stink compared to D-A-F.

Strengths: This application does a more complete defrag of the drives(s)and allows you to see which files are the fragged the most. The application allows you to defrag individual files and remove the remaing file fragments.
Weaknesses: I could not find any weakness and it works better that other defrag freeware that I have used in the past.
Overall Evaluation: Yes, this application does take just a bit longer than the windows system, however it does a much more complete job of defragging and that is the real benefit. For those worried about 4 hour defrag times, don't! If you are defragging a 1TB drive 60% full, well then duh, it's going to take that long. Try it .... I think you will be pleased.

Strengths: Runs faster than XP's defragmenter. 4 hours?? When was the last time he ran any defragmenter?
Weaknesses: I cannot find any.
Overall Evaluation: I do not see this program actually increasing any used space on my hard disk. I ran XP's defrag soon after this one and the used/free space is the same. Unless someone is seeing something I am not I see no increased use of any hard drive space running this on a laptop and a desktop. Possibly the 4 hour result is FAT32 vs NTFS? I find this runs real well on a FAT32 file system which is OEM on one of my XP laptops.. Win XP's defrag takes forever on a FAT32 file system. On a NTFS file system (as on my desktop) this seems to really fly also. My point is: if you want a fast defrag on an FAT32 file system this works!

Strengths: User interface; clean, friendly. Informaton regarding contents of sectors and file fragmentation.
Weaknesses: Does defrag to some extent but behavior is suspicious. Runs much longer than it should and increases (yes, increases not reduces) hard disk space used. Increased used disk space by 3Gig in one defrag when run with 149 fragmented files and 441 fragments, and appeared to be relocating every sector, one at a time. Ran for almost 4 (yes 4) hours. Puzzling...or worse.
Overall Evaluation: Hard to say. I'm not sure if this program is just buggy or worse.

Strengths:
Weaknesses: It seems to get 'confused while defragging( only a 1/3 of the hd is occupied!); it's actuall increased the number of frags while in use-repeatedly. I hate MS defrag, but its a hell of a lot more efficient than this thing. Its a shame that it's not up to par with Piriforms "Ccleaner" (excellent tool!)
Overall Evaluation: MS defrag is better, hard as that is to believe.

Strengths: It seems bulletproof, auto updates (if you let it). But it has visual display so you can see what its really doing. Not like Windows Defrag where you don't even know if its working at all.
Weaknesses: It can be a bit slow (but faster than Windows Defrag). And you might have to run it twice if you have LOTS of files.
Overall Evaluation: Its the best defragger I've ever used, and its from a reliable company. PS...FRRREEEEEEEEEEEEE !!!

Overall Evaluation: I was skeptical at first with a free defragger, but this one seems to do a quicker and more thorough job. It detected approximately 20% more fragmentation than XP's defrag utility. I would recommend this download.
