UltraDefrag can defragment both FAT and NTFS disks with just a couple of restrictions:
It cannot defragment FAT directories, because their first clusters are immovable.
It cannot defragment master file tables (MFT), because their first 16 clusters are immovable.
However, the program optimizes those files placing their fragments close to each other behind the first one.

UltraDefrag can be used on Windows XP/Vista/7/8/10 as well as Windows Server 2003/2008/2012/2016.
Elder versions of the program (prior to v7) can be used on Windows NT 4.0 and Windows 2000 as well, with some limitations.
Additionally UltraDefrag for Linux exists which is an independent port of the program based on NTFS-3G capabilities.
