UltraDefrag is an open source disk defragmenter for Microsoft Windows. It removes the file fragmentation issue speeding up the PCs which require less mechanical work to read continuous information from disks. UltraDefrag can repair almost everything including documents which are usually locked - it starts inside the boot process when the files are not used by the system.
UltraDefrag has the next features:
- simple but useful defragmentation algorithms
- secure environment avoiding files corruption
- defragmentation of secured paging and hibernation files
- defragmentation of NTFS metafiles (MFT) and streams
- defragmentation of disks having designated fragmentation level
- flexible filters enabling exclusion of files by numerous criteria
- one click defragmentation via Windows Explorer context menu
- multilingual graphical interface (more than 60 languages available)
- strong command line interface
- planned defragmentation (using Windows Task Scheduler)
- automatic termination when designated time interval elapses
- automatic hibernation or shutdown after the job completion
- tiny size of installers (about 1 MB)
- availability of portable packs needing no installation
- complete assistance of 64-bit variants of Microsoft Windows
- allowed permission to use and share the program
UltraDefrag is able to defragment FAT or NTFS drive with just a couple of restrictions:
- Not able to defragment FAT directories, because their first clusters are immovable.
- Not able to defragment master file tables (MFT), because their first 16 clusters are immovable.
- Very fast.
- Can defragment multiple partitions at the same time.
- Multiple installation files for different variants of Windows.
