JKDefrag: Best Freeware to Optimizes Hard disk


JKDefrag is one of the best free disk defrag utility for Windows 2000/2003/XP/Vista. It is easy to use, has low memory usage, fast and extremely efficient. It can defrag hard disks, floppy disks, memory cards and everything else that appears as disk to windows. The main features of JKDefrag are:

  • Completely free and open source.
  • Easy to use. No bells and whistles.
  • Fast and efficient.
  • Uses standard defragmentation API by Microsoft to move files. It sends the “which file to move command” to the API. This makes it highly secure.
  • A very good feature is screensaver defrag. This feature defrags the disk while the screensaver is running.
  • Can be run from portable devices, CDs etc.
  • Also has command line version to run the tool on network, schedule tasks etc.

The current version is v3.34 which can be easily downloaded from their website. Although there are some bugs, but most of these are due to API limitations and not necessarily the bugs in JKDefrag. The setup file is only 465kb, so this one will also be welcomed by the dial up users amongst us :)
