Most of us add and remove programs and files daily in our computer. But soon you might notice slowness in your system’s performance. That is caused some files are left fragmented while removing or adding new applications.

The built-in Disk Defragmenter in Windows is not so good and comes with limited options, that are not enough to fully analyze and defrag your hard disk drive.

UltraDefrag is powerful open-source defragmentation tool for Windows. It is very fast, because the defragmenting is done by kernel-mode driver. There are three UI interfaces: graphical, console and native.

The GUI is very useful, because it represents your filesystem visually as a color coded cluster map. The console is another option for those that prefer the command line. It also allows you to run UltraDefrag from the task scheduler and scripts. Finally, the native executable will run at boot time in a manner similar to CHKDSK.

Some of its features include:

  • Very fast defragmentation, the work is done via a kernel mode driver which has an optimal defraging algorithm.
  • Very small engine written in pure C.
  • Nice graphical interface – compact and functional.
  • Safety, because the file moving is accomplished with Microsoft’s own Defrag API.
  • Simple to use.
  • Ability to generate html reports of fragmentation status.
  • Ability to include/exclude files based on simple filters.
  • Native x64 support.

It is a very small, simple utility with powerful features. Download it from the link below.
