Download JkDefrag 3.34

A few days ago, version 3.34 of Jkdefrag, an open source hard drive defragmenter, was released. It is being developed by Jeroen Kessels and is available for Windows 2000 or higher in both a 32-bit and 64-bit version. The download is only 452KB in size and for that you get a version that runs in a DOS box under Windows, a version that can be started from the command line and a version that starts when the screensaver is activated. Those who prefer a graphical user interface can use JkDefragGUI. Below is what has changed in Jkdefrag since the previous entry in the Meuktracker:

Changes in JkDefrag version 3.34

• 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.

Changes in JkDefrag version 3.33

• Fixed a bug in the Windows version that for some users caused the display of the diskmap to get stuck.
• Fixed a bug in the forced-fill optimization that caused the program to skip fragments that were left by filling a gap with a part of the fragment.
• If the volumename of a disk cannot be determined then the program will now fallback to using the mountpoint of a volume to open a handle.
• If the user specifies a short input mask without a wildcard, for example “C:” or “C:\”, then the input mask is rewritten as “C:\*”.
• Fixed a bug where the special “DisableDefaults” spacehogs mask only disabled the masks, but not the “Files bigger than 50 megabytes”” and “Files not accessed in the last month” criteria.
• Bundled some language-specific SpaceHogs masks into “?:\\*\\Installshield Installation Information\\*”.
• Moved the “Volume ID” message for FAT disks from debug level zero to 6.

Changes in JkDefrag version 3.32

• Fixed a bug in the FAT scanner that caused the program to crash on volume names shorter than 9 characters.
• Simplified the rules that automatically change the mask that selects which disk/folders/files must be processed. It now simple prepends and appends an asterisk if there is no asterisk yet.
• Some minor changes in the graphics code.
• Fixed a bug in the commandline version that showed zone numbers 0…2, instead of 1…3.

Changes in JkDefrag version 3.31

• Fixed a problem in the Windows version, it now redraws the diskmap when the user changes the size of the window.
• Added special cases to the exclude masks to recognize a drive letter without an asterisk, for example “c”, “c:”, or “c:\”.
