Diskeeper is a disk defragmenter for Microsoft Windows. Diskeeper 2007 represents a quantum leap in system performance, enabling you to run your computer at the height of its potential, 100% of the time, and for the life of your systems.

The main features of Diskeeper 2007 (now compatible with Vista) include:
- InvisiTasking, which is coined from "invisible" and "multitasking" and is a technology which allows any system maintenance task to run invisibly in the background.
- New real-time defragmentation that automatically and transparently handles fragmentation as it occurs providing maximum system performance at all times.
- I-FAAST™ 2.0 (Intelligent File Access Acceleration Sequencing Technology) which dramatically increases file access by up to 80% above and beyond the improvement of defragmentation alone.
- Terabyte Volume Engine™ 2.0 - Powerful defragmentation for high capacity & high traffic servers with disk volumes containing hundreds of thousands to millions of files (e.g. NAS, RAID, and SAN). Also allows unobtrusive, thorough free space consolidation on busy 24/7 servers.
- Automatic online directory consolidation that boosts anti-virus scans and back-up speed. Every system will benefit from Diskeeper 2007. A site-wide Diskeeper installation will improve performance and reliability on all systems.
