UltraDefrag 7.0.2

UltraDefrag Icon

UltraDefrag is a fast, advanced and reliable open source disk defragmentation utility for Windows, which supports defragmentation of locked system files by running during the boot process. When files consist of many little fragments scattered around the disk the computer needs more mechanical work to read them. Because of that the disk access becomes slower.

UltraDefrag reduces the file fragmentation, thus it makes disk operations faster. Also the program can optimize a whole disk by placing small files close to each other, sorted by path (or other criteria). After the disk optimization less mechanical work is needed to read groups of small files. This reduces startup times of many applications including web and photo browsers.

UltraDefrag Key Features:
  • Easy to use GUI
  • Ultra fast and reliable
  • Efficient defragmentation algorithms
  • Defragmentation of locked paging and hibernation files
  • System files defragmentation
  • Powerful command line interface
  • Boot Time Defragmentation
  • Console interface for batch processing
  • Defragmentation via Explorer context menu
  • HTML reports
