UltraDefrag is a disk defragmenter for Windows, which supports defragmentation of locked system files by running during the boot process. It is easy to use without any complicated scripting or a huge load of configuration settings. You can filter the files processed by size, number of fragments, file name and path. You can terminate the process early by specifying an execution time limit.

Features

  • Automatic defragmentation of disks
  • Automatic disks cleanup before defragmentation
  • Graphical user interface to follow the process visually
  • Boot time defragmentation for system files processing
  • Console interface for batch processing or setting up scheduled tasks
  • Process single files, folders or drives from the Explorer's context menu
  • Specialized processing algorithms for each situation
  • Available for both 32bit and 64bit Windows
  • Optional quick test mode to get a preview of the resulting disk usage

    1 - It seems to be good. I tried it years ago, several times (off-&-on) through various operating systems, yet, STILL -- they can't get it to shut-down your computer, when done defragging! WHYYY would I want to buy that problem? 2 - Plus, why is the g.u.i. sooo small? I have to wear/use my reading-glasses, to see it (read the button pop-ups). Perhaps they could increase the over-all size? 3 - Also, i've begun replacing my h.d.d units, with s.s.d.'s (which we're NOT supposed to de-frag) sooo -- wht now? What's to become of this software? SOME-ONE, please advise? thanks much! kbr
