JkDefrag 3.33

Bookmark and Share
JkDefrag is a disk defragmenter and optimizer for Windows 2000/2003/XP/Vista/2008/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.

JkDefrag is based on the standard defragmentation API by Microsoft, a system library that is included in Windows 2000, 2003, XP, Vista, and 2008. Most defragmenters are based on this API, including commercial defragmenters. Basically all JkDefrag does is send "move this file to that location" commands to the API.

It does not touch the disk by itself, and is therefore extremely solid. If your disks use NTFS then you're even safe when the computer crashes in the middle of defragmenting. 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 (disk crash), and/or overheating (disk, power supply, controller chipset, etc.).
