JkDefrag is a free 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.

Changes:

• Upgraded to the Microsoft Visual Studio 2008 compiler.
• Logfile is now written in UTF-8, it used to be ANSI.
• Changed the default font into a smaller font.
• A change in the display code to respond faster to multiple redraw requests, for example when the users resizes the window.
• Rewrite of the subroutine that finds combinations of files to fill a gap, to make it faster.
• Changed the algorithm for "-a 6" (move to end of disk) to better fill gaps.
• Changed the way disks are accessed to accomodate special kinds of disks, such as virtual and encrypted disks.
• Bugfix in the screensaver for very long commandlines.
• Change in the disk analyzation code to fix a "zero bytes per cluster" problem.

wah thanks sotong168!! now JKDefrag looks more professional looking...and now can select which partition disk to defrag instead of defrag all partition!

JkDefrag 3.36

JkDefrag v3.36 (August 31, 2008)
Changes:

• Reverted back to an old Microsoft Screensaver library. The 2008 compiler has a library that is incompatible with Windows XP ("The procedure entry point ChangeWindowMessageFilter could not be located in the dynamic link library USER32.dll").
• Fixed a problem with extremely long path names.
