UltraDefrag: Free Disk Defragmentation Tool

A free disk defragmentation tool for Windows to optimize file system performance, speed up access times and improve overall system response.

What is UltraDefrag?

UltraDefrag is a powerful, free defragmentation tool for Windows. It works by analyzing the layout of files on your hard drive and then rearranging fragmented files so that all parts of a file are contiguous. This helps to optimize file system performance.

Some key features of UltraDefrag include:

  • Comprehensive disk analysis to identify fragmented files and optimization opportunities
  • Multiple defragmentation algorithms like quick, standard, and full optimization methods
  • Ability to defragment the master file table (MFT) and registry hives for more thorough optimization
  • Boot time defragmentation option to run before Windows loads
  • Graphical map of disk blocks for easy visual representation of fragmentation
  • Integration with Windows task scheduler for automatic, scheduled defragmentation

By consolidating the parts of files into contiguous regions of the disk, UltraDefrag can speed up file access times remarkably. Frequently accessed system files also load much faster after defragmentation. The end result is improved disk performance, faster loading applications and files, and an overall more responsive system.
