UltraDefrag Review

Felix Cheng
A free and open source disk defragmenter
A review of UltraDefrag by Felix Cheng

UltraDefrag is a free Windows disk defragment utility which utilizes the same API which is used by virtually all other disk defragmenters which is provided by the Microsoft Windows operating system.

Though it defragments disks the same way Windows does, it includes several new and improved features which makes defragmentation more complete and puts more control into the hands of system administrators and users alike.

The graphical user interface doesn't take much time to get used to as it contains several standard features which most other defragmenters use.

When you run the program and choose to defragment a hard drive, you'll be given a couple of different options after hard drive analysis has completed. It will display a report (available in the form of an HTML file) which displays which files are fragmented and their locations. If you want to complete your hard disk defragmentation process quicker, you can also choose to skip specific files.

This program includes support for 64-bit operating system natively, so if you are running an x64 version of Windows, simply download the x64 installation file and you're good to go.

UltraDefrag features and highlights:
  • Currently FAT, exFAT and NTFS are supported
  • Defragmentation of files and folders including system files and file system meta files
  • Full optimization of the drive, which processes all files despite of their fragmentation
  • Quick optimization of the drive, which mainly processes fragmented files
  • MFT optimization, which processes the MFT only
  • Filtering of files to process by name, fragment count and size
  • Drive processing can be interrupted automatically after a defined amount of time
  • User defined log file creation, which highly simplifies reporting bugs
  • Drives needed to be checked by CHKDSK are excluded

UltraDefrag is licensed as Freeware for Windows (32-bit and 64-bit) operating system / platform from hard drive defrag software without restrictions. UltraDefrag 7.0.2 is available to all software users as a free download (Freeware).
