O&O Defrag Server Edition screenshotThe new O&O Defrag Server Edition program for Windows Server enhances your hard disk and safely packs file fragments together. Thanks to the new background monitoring feature, O&O Defrag avoids the fragmentation at source. Recently added and modified files are examined and defragmented whenever they are not being used. O&O Defrag makes sure that your hard drive is continually performing at its peak.

O&O Defrag can be administrated centrally in combo with O&O Enterprise Management Console 2. It not only enables you to run defragmentation tasks on particular computers and networks, but also the remote installation of O&O Defrag.
