JkDefrag

CNET Editors' review

This is a freeware defrag tool for those less interested in speed than in simple operation. JkDefrag does away with menus, options, and configuration settings. The program comes as a Windows GUI tool, a command line application, and a screensaver. Ultimately, each method operates exactly the same way.

Double click the JkDefrag executable and the program starts. There is no need to tell it which drive to defrag or whether to place folders first. JkDefrag will start processing all mounted fixed volumes it finds. It will slowly analyze and slowly defrag each drive. Don't expect to run this application over a coffee break. As it runs, the program displays a hard disk map color-coded to show each block in any of seven states. The command-line and screen saver applications work exactly the same way and at the same speed. The screen saver version is set the same way you would any other screen saver. Set it correctly and your co-workers will see you are really defragging your drive and not lost in thought about your basketball brackets.

JkDefrag addresses the old adage about products. You can have two of the options of fast, cheap or good, but not all three. JkDefrag is slow, free, and good.

    Version: JkDefrag 3.16

    Pros

    Really effective in moving all your files into the outer ring of your disk
    Which has the highest reading speed

    It does speed up your PC !

    Cons

    Put a lot of strain in your PC

    You can mess up your disk with this software

    Summary

    Nice for busy people who want to keep its PC in shape
    But over usage means death for your hard drive

    "Un defragmentador sorprendente"

    October 14, 2008  |   By rgonzalezco

    Version: JkDefrag 3.16

    Pros

    Muy eficiente

    Cons

    Un poco lento en las primeras oportunidades, carece de una interfaz integrada y sencilla.

    Summary

    Este programa me sorprendió por los resultados en la computadora. Aunque es una máquina antigua, la optimizó muy bien. Ya lo había usado anteriormente, pero no me convencía. Ahora, sí.

    "A great defrag tool!"

    September 26, 2008  |   By EyeWierd

    Version: JkDefrag 3.16

    Pros

    JKdefrag is extremely simple, easy to use, and still gives you the choice to analyze your hard drive, defragment, or both! It greatly helps out your computer speed, and will in addition get rid of unesasary files that you do not need.

    Cons

    It takes a VERY long time to defragment/analyze your computer compared to other defragers, especially the first time using it (which might take all day if you use a lot of memory space).

    Summary

    The product is great for everyone! After I used it, programs and games would open faster, run smoother, and altogether make your computer better. I think it is well worth the long 6-9 hour wait after you see what it has done to your computer. Absolutely one of the best free defragers I've ever used before.
    It even displays a bit-map image of what is happening with your Hard Drive as it is being processed. It displays colours and patterns to show where files are supposed to be, where they are missing, and where the Hard Drive is being patched up to improve the computers speed. This product is free, slow, effective, and altogether great!

    "Seems to be a great defragger, but..."

    July 29, 2008  |   By jastb

    Version: JkDefrag 3.16

    Pros

    Apparently does a much better job of defragmentation than the program that comes with windows XP. Once it's been used a few times it's also fairly rapid.

    Cons

    There is no explanation of the 'wash' feature of the program, that I could find.. That can be disconcerting to say the least!

    Summary

    The fine running defrag feature is a one click, no worry program. Not so the 'wash'. I confess I didn't know I needed a wash, but Gizmo Richards thought t was a good thing, so I gave it a try. The feature said that the more it was used the better job it would do, and had a place to enter the number of times you wanted the wash run. I typed in 3, and left for a few hours. Came back and I had a warning that said my memory, which I usually keep between 78-80 GB was down to 65 MB. Trying everything that I could think of I could not figure out how to get the memory back, and ended up reinstalling the Windows XP system.

    I thought the problem was a recently installed Joost download that had taken it upon itself to download 'favorite programs'.. Eventually I got around to redownloading JkDefrag GUI, and eventually tried the wash feature again. This time after about half an hour I decided to check my memory.. I was down to 27 GB, so I immediately stopped the wash feature. I tried many things to reclaim the memory.. I believe the one that did work was to click START, then TURN OFF COMPUTER, then RESTART.

    Apparently the wash feature works by completely filling up the hard drive with garbage and then removing the garbage for a shiny clean hard drive. At least this is the way I understand it from what little information I could find here and there. I'm not a technician, but I didn't just fall off the computer truck yesterday either. It seems to me there could be a much better explanation of the wash feature and (I'm guessing) the rest of the features that I'm afraid to get involved with. At this point all I do with JkDefragGUI is defragment. Period.

    "Best defrag tool"

    May 27, 2008  |   By asd264

    Version: JkDefrag 3.16

    Pros

    Most effective even though it's not the fastest

    Cons

    I recommend getting JKDefrag GUI which has JKDefrag but (as the name implies) with a GUI

    "I haven't seen any better"

    April 10, 2008  |   By thosthos

    Version: JkDefrag 3.16

    Pros

    I've tried all the free defraggers + Diskeeper Professional and think JkDefrag beats them all. To call it slow doesn't make sense. The only slow part is the optimisation and that takes a lot of time the first time you use it because it's relocating more or less everything on your disk. I used the recommended option -a7 to set up the disk and then -a3 each day automatically after that. It's terrific, not quite all the bells and whistles of Diskeeper, but just as effective and considerably easier to use (and free!).

    Cons

    The display put me off a bit at first. But that's because it's not the same as every other defragger. It's actually much more informative than most.

    "Simple, small, and works well"

    March 25, 2008  |   By MrkcuhC

    Version: JkDefrag 3.16

    Pros

    It is simple to use, I fire it off occasionally before I go to lunch, when I come back, it has pretty much done all my drives.

    Cons

    Not fancy, not much in the way of options, but perhaps that is really a strength.

    "Excellent"

    March 11, 2008  |   By einstein999123

    Version: JkDefrag 3.16

    Pros

    It's fast, small, easy (just click jkdefrag.exe) and thorough. What more can I say? An excellent freeware.

    Cons

    The interface could do with some improvements, but it really isn't that important.
