JkDefrag 3.17

Posted on Sunday, August 26 2007 @ 01:04:11 CEST by

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 several 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.

  • NTFS disks are now analysed by directly reading the MFT from disk. This is a lot faster, and finds more system files.
  • NTFS streams are now supported and will be defragged and optimized.
  • Added an icon.
  • Added a version info resource to the executables.
  • Added a manifest so Vista will always run JkDefrag with administrator privileges.
  • Added support for short filenames. The masks now also work for short names, for example "PROGRA~1" (instead of "Program Files").
  • Spacehogs are now shown in dark-green, regular files in light-green. Allocated space is now shown in grey, instead of black.
  • Bugfix in redrawing the diskmap, to properly handle redraw-requests while redrawing.
  • Files larger than 1 gigabyte are now closed and re-opened at 1 gigabyte intervals.
  • Change in the fast optimize algorithm. When a gap cannot be perfectly filled the program now takes the highest file on disk that will fit, instead of the largest file. This reduces the amount of data moved and optimization will finish quicker.
  • Added a special exception for the "?:BootAuth?.sys" files used by DriveCrypt.
  • Added a few extra lines to the status report.
  • The logfile now shows which command line options were used.
  • Added to the default list of spacehogs:
    • ?:RECYCLED* (FAT on 2K/XP)
    • ?:$RECYCLE.BIN* (Vista)
    • ?:WINDOWSEhome*
    • ?:WINDOWSFonts*
    • ?:WINDOWSHelp*
    • ?:WINDOWSSpeech*
    • ?:WINDOWSSymbols*
