    Duration of ownership: 3 Months

    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.

    Strengths: None

    Weaknesses: It can't finish. Takes two hours to go from 68% to 71% and then does not progress.

    Overall Evaluation: Usless. Perhaps it is not ready for 64-bit Vista.

    Strengths: Nice view of drive

    Weaknesses: Vista 64 - ran for 48+ hours doing nothing but creating 4000+ files in TEMP directory, all same size. CANCELLED and ran MS version which finished in 2 hours.

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

    Strengths: Simple display, lots of information, individual file defragging.

    Weaknesses: SLOW! Stick with Auslogics defragger or Norton 360

    Overall Evaluation: I see no good reason to use or keep it.

    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 !!!

    Strengths: free & fast

    Weaknesses: none so far

    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.
