What UltraDefrag is

UltraDefrag 15 is a paid Windows disk defragmenter designed to improve PC performance by rearranging fragmented files. It can process a whole disk or selected files and folders from Windows Explorer, and it supports NTFS metafiles and data streams, including the Master File Table. A boot-time mode can handle locked files such as page, swap, and hibernation files. Its optimization tools move files toward faster disk areas and defragment free space; these tasks can run on a schedule or while the computer is idle. For SSDs, it uses TRIM and excludes files with fewer than 20 fragments by default. SMART monitoring tracks disk health, alongside integrity and thermal protection features. Cleanup tools remove temporary files before processing and can clear obsolete Windows update files. UltraDefrag also offers command-line task automation and a portable edition that 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.
