UltraDefrag uses Microsoft's defragmentation API and works on Windows NT, 2000, XP, Server 2003, Vista, and 7 operating systems. It supports FAT12, FAT16, FAT32, exFAT, and NTFS file systems. As of March 2013 Windows 8 is still not tested with UltraDefrag and the boot-time defragmentation utility will not work on Windows 8 either.

Famous quotes containing the word features:
“The features of our face are hardly more than gestures which force of habit made permanent. Nature, like the destruction of Pompeii, like the metamorphosis of a nymph into a tree, has arrested us in an accustomed movement.”
—Marcel Proust (1871–1922)
“It is a tribute to the peculiar horror of contemporary life that it makes the worst features of earlier times—the stupefaction of the masses, the obsessed and driven lives of the bourgeoisie—seem attractive by comparison.”
—Christopher Lasch (b. 1932)
“Art is the child of Nature; yes,
Her darling child, in whom we trace
The features of the mother’s face,
Her aspect and her attitude.”
—Henry Wadsworth Longfellow (1807–1882)
