JkDefrag is a disk defragmenter and optimizer for Windows 2000/2003/XP/Vista/X64. Completely automatic and very easy to use, fast, low overhead, with several optimization strategies, and can handle floppies, USB disks, memory sticks, and anything else that looks like a disk to Windows. 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), versions for Windows X64, and the complete sources.

Changelog:

• Re-fixed the "DisableDefaults" bug.
• Partial undo of the change that uses the mountpoint of a volume. It was causing problems during the automatic scanning for disks to be defragmented.
• Pushed the "Zone calculation" messages down to debug level 4.
• Fixed the VisualC example project.
