Windows Disk Defragmenter is a computer program included in Microsoft Windows designed to increase access speed (and sometimes increase the amount of usable space) by rearranging files stored on a disk to occupy contiguous storage locations, or defragmenting. The purpose is to optimize the time it takes to read and write files to/from the disk by minimizing head travel time and maximizing the transfer rate.

    I just disabled it - it's useless and just bloating Vista - I prefer using jkdefrag or smartdefrag instead

    Okay but not great. Better to use Defraggler which is free.

    Windows disk defragmenter.. I use this after I download large files to my computer.. Piriform's defraggler gets used when I download a lot of tiny pictures etc.

    +For Diskeeper, set it on automatic mode and its does the job without problems even as you use the PC.

    I think it works well. It is slow, and prefers to be alone with its doings (don't do stuff while its doing stuff). But, its nice. But, others can be better.

    Better than nothing, but I'd recommend using a full blown disk defragmenter, such as Diskeeper.
