UltraDefrag is designed to defragment FAT and NTFS drives, including registry hives and paging file. Said to provide good speeds and reliability, this HDD tool features an optimization module created to rearrange files despite their fragmentation in three different modes: full optimization, quick optimization and MTF optimization. These processes can be interrupted and resumed later on. Furthermore, multiple hard disks may be selected for defragmentation in the same time.
Whereas most file defragmenters work alongside windows, this one activates itself during Windows boot, thus being able to move even blocked system files.
Paths or chosen criteria are applied according to needs during defragmentation.
