- Windows XP Home and Professional, 2000/2003 and Vista supported

Hard disks are by far the slowest component in your computer. CPU and memory work much faster than hard disks because they do not have moving parts. Therefore fragmented disks often become a bottleneck of the system performance.

Besides causing slowdowns, fragmentation makes the hard drive disk heads move frequently when reading files which leads to freeze-ups and system crashes. It is important to keep your disks defragmented and optimized as much as possible.

Changes in version 1.3.7.235:
- adds a new feature: ability to remove temporary files before defragmentation
- adds a new feature: ability to set the resource usage (low, normal, high)
- improves disk defragmentation speed
- improves GUI design and fixes Windows Visa fonts
- improves disk fragmentation map
- various bug fixes and optimizations
