JkDefrag 3.11

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 commandline 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 this version:

- Fixed a bug that caused files to be classified in the wrong zone, causing several problems.
- Fixed a bug where the list of files was not cleared between disks.
- Re-applied "The versions now also detect if another version is running" change from v3.9 that was accidentaly deleted in version 3.10.
- Reduced the size where huge files are treated in segments to 1Gb, in a further attempt to work around a suspected bug in the Microsoft defragmentation api.
