CNET Editors' review
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.
Publisher's Description
From CodeStuff:
JkDefrag GUI is a graphical user interface program for the open source hard drive defragmentation program JkDefrag. 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.

"Unable to rate (Only 1 Star) did not install. Cons."
Version: JkDefrag GUI 1.15
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.

"Very good, very efficient, very trustworthy"
Version: JkDefrag GUI 1.15
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.

"Best defragger I've come across"
Version: JkDefrag GUI 1.15
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
