Diskeeper is far and away the most recommended automatic defragmenter for Windows. Diskeeper Lite is a manual-only version that will introduce you to this powerful system maintenance tool.

IMPORTANT:
Diskeeper Lite includes the same advanced defragmentation technology used in Diskeeper full version. This program is the fastest defragmentation program ever built. Full version Diskeeper has 5 priority levels and can be easily set to run transparently in the background, even during peak production times. However, Diskeeper Lite is locked at the "normal" system priority level and may slow other online operations.

While Diskeeper Lite far outperforms any other manual defragmenter available, the only true solution to the performance and stability degradation caused by fragmentation is the powerful "Set It and Forget It"® automatic functions in Diskeeper full version.

To find out how much performance you are being robbed of on your system, simply highlight the drive in the Diskeeper display, then click "Analyze." The results of this analysis will show you how much fragmentation and how much performance degradation you are suffering from. Once the analysis is done, click “Defragment Now” to start a manual defragmentation job.
