For about as long as there's been a Windows, developers have been targeting the disk defragmentation utility for improvement. JkDefrag is a free, open-source defragmentation utility; JkDefrag GUI is a graphical user interface version that makes the powerful tool as easy to use as the built-in Windows feature and its many competitors.

JkDefrag GUI opens with a compact properties dialog that serves as a primary control interface. We selected what Actions we wanted JkDefrag to perform and which of our drives to check from drop-down menus and started the program. A compact view opened, displaying the program's progress in a color-coded bit map and counters. Clicking the program's system tray icon called up a menu with basic controls, a key to the display's color coding, and a menu for selecting what you want it to do when it's finished with the current job. The defragmentation process didn't seem to take significantly more or less time than other tools, though the program has some nice features, such as moving directories to the front of the disk and reclaiming MTF reserved space when the disk is full. JkDefrag is optimized for daily use and can be run automatically at startup or other times, and it can be used as a screensaver, too. It's as robust and reliable as any defrag tool based on the Microsoft API, which is pretty much all of the competition, so it won't delete the wrong files or otherwise mess up your disks. The tabbed JkDefrag interface is easy to manage, despite its many options.

JkDefrag GUI is a powerful, flexible defragmentation option that is accessible and as easy to use as other Windows disk defraggers. Since it's open-source freeware that is supported by a community of users (including a forum), it's always evolving and keeping pace with real-world issues.

Unable to rate (Only 1 Star) did not install. Cons.
CopmanJanuary 17, 2012
Pros
Nothing at present did not install.
Cons
I checked the download at Virus Total and Jiangmin Anti Virus ( one of 42 scanners )stated that this had Trojan/Refroso.ijp. This may well be a false positive scan, but until I am sure I will not install the programme.
Summary
Check it yourselves.
Outstanding. Works flawlessly

Pros
Does everything it's set out to do.
Cons
Gui interface a bit baffling for some of us
Summary
Good if you need a GUI
drjohn72July 10, 2011
Pros
Clear, simple
Cons
Not sure I need a GUI
Summary
Downloaded by mistake - just wanted jkdefrag - this doesn't add much for me, but there's no problem with it
Very good, very efficient, very trustworthy
artemisoflightJanuary 14, 2011
Pros
Simple to use, but detailed enough to satisfy the advanced user. The computer is faster. Works far better than Microsoft's defragment program. More versatile and less pushy than Auslogics, though both programs do an excellent job.
Cons
For the beginner, it may take a little time to learn how to use all of the features.
Summary
I really like that my computer works properly. I do a lot of file juggling and deleting. I work on my laptop and, though I have massive amounts of storage space available, I cannot afford to have the system crash. JK Defrag keeps my system running smooth and efficiently. I have been using it for two years and I couldn't be more pleased.
works great

Pros
works really great
Cons
Doesn't not work really great
Summary
Use it!
Best defragger I've come across
physiozNovember 18, 2010
Pros
I don't have a jam-packed HDD. Still over time my PC slows. Despite the numerous claims made by different vendors etc, this is the only Defrag software that consistently makes a NOTICEABLE difference to my PC's speed. (Windows 7, 64 bit)
Cons
Only caveat, the optimise monthly option takes several hours to run, probably because I don't defrag daily or even weekly sometimes (Windows 7, 64 bit). This is not an issue as I run it overnight.
Summary
Significantly speeds up PC, stable and very simple to use
A must have
KovolainenNovember 30, 2009
Pros
Very good, especially with the GUI to configure settings
Cons
Needs an installer
Summary
works well
Silent_SpecterOctober 27, 2009
Pros
it got my HDD from 90% file fragmentation to completely defragmented, now it runs so much better, especially for videos.
Cons
while defragmenting there are not too many options to change what you can see, and little things like that
Summary
excellent defragger
r-cnetAugust 19, 2009
Pros
fast and effective
Cons
does not consolidate free space
Summary
works well and is fast and easy to use
Excellent!

Pros
Easy to install & use. Noticable improvement in performance
Cons
First time running it can take quiet a while. As warned.

Developer’s Description

It enables users to easily use JkDefrags powerful defragmentation operations, schedule defrags, perform system file defrag operations on startup, as well as set a wide spectrum of defrag options. It can also be used to quickly install JkDefrags screensaver defrag, an option that kicks in the defrag process and displays it as a screensaver whenever the computer is idle.
