Looking for an alternative to the Windows defrag utility [closed]

Defraggler from the same guys who brought you CCleaner and Recuva! All are great pieces of software.

I was using O&O Defrag for years, but recently switched to PerfectDisk. PerfectDisk is still able to defragment even when the hard drive has very little free disk space.

DisKeeper is good.. has a managed version for enterprise. http://www.diskeeper.com/

"O&O Defrag, http://www.oo-software.com/home/en/products/oodefrag/index.html.

It will actually move files around (instead of just
defragging individual files). In this way files that are in
the same folder will all be physically be close on the disk.

It can also defrag files that are in use by Windows (e.g.
the MFT) by doing defragging at boot time. This however requires
that the defragging runs as a result of being defined in a
job.

I can recommend it. I have used it for many years without
any problems and it is not intrusive; there is no noticeable
degradation in performance while it runs."
