Free (released under the GNU General Public License) disk defragment and optimize utility for Windows 2000/2003/XP/Vista/X64. Completely automatic and very easy to use, fast, low overhead, with two optimization strategies, and can handle floppies and USB disks/sticks. Included are a Windows version, a command line version (for scheduling by the task scheduler or for use from administrator scripts), a screensaver version, a DLL library (for use from programming languages), and versions for Windows X64. JkDefrag is based on the standard defragmentation API by Microsoft, a system library that is included in Windows 2000, 2003, XP, and Vista. All defragmenters are based on this API, including commercial defragmenters. JkDefrag is therefore very solid and there is no risk of losing data. You can stop the program at any time, it will finish the current file in the background. If your disks use NTFS then you're even safe when the computer crashes in the middle of defragging. Nevertheless, it's still a good idea to backup before defragmenting, just like with other defragmenters, because the heavy use of the harddisk may trigger a hardware fault.

Changes in
JkDefrag v3.23 (August 31, 2007)

- Yet another fix of the out-of-sequence problem that keeps plaguing a small set of users. I have deleted the previous fixes and added code that will delay the processing of the AttributeList in the MFT until the Data attribute has been processed.



- Fixed the test for the NtfsDisableLastAccessUpdate registry key (see v3.19). If the key is not available the program defaulted to ignoring the LastAccessTime.

nice FREE defrag program ... i been using this a little while now... seems overall nice and lite even though overall i feel it needs to have a better user interface and have analyze options etc like most defrag programs do... if it could do that i feel it would be a pretty solid defrag program.

Well, it has always had an analyze option (commandline parameter -a 1). It's in the manual.
And well, the user interface, do you mean that you don't have to type all the parameters and such? You could make something in AutoIT, Visual Basic, C++ or whatever. I think there's a GUI available somewhere already though.

You could always go with UltraDefag v1.0.5 - it's free and opensource. UltraDefag at Sourceforge

This is a really nice defrag program, looks awful graphically but works great and the screensaver module is super handy.

looks like it is still not stable yet. stick to 3.16 for now.

So far, v3.23 is running perfectly for me. I'm keeping it for now.

There hasn't been an update in hours
