What UltraDefrag is
UltraDefrag 15 is a paid Windows disk defragmenter designed to reassemble fragmented files and support disk optimization. Users can defragment selected files and folders from Windows Explorer, while NTFS processing includes metafiles, data streams, and the Master File Table. A boot-time mode handles locked page, swap, and hibernation files. Optimization moves files toward faster disk areas, defragments free space, and can run automatically during idle periods or on a schedule. For SSDs, files with fewer than 20 fragments are excluded by default and TRIM is used. SMART monitoring checks disk health, with integrity and thermal protection features. Cleanup tools remove temporary files before processing and obsolete Windows update files. A command-line interface supports automation, and a portable edition runs from a USB stick without installation. The maker lists Windows 11, 10, 8.1, 8, 7, and several Windows Server versions in 32-bit and 64-bit editions.
