UltraDefrag is a disk defragmentation utility that runs on Windows. This is the first open source defragmenter with full system lock file defragmentation support. Actually all files including a collection of registry and paging files can be processed by UltraDefrag during the Windows boot process.
When a file consists of many small fragments scattered on a disk, the computer needs more mechanical work to read it. Therefore disk access is slower.
This application reduces file fragmentation, making disk operations faster. In addition, this program can optimize all disks by placing small files close to each other, sorted by path (or other criteria). After disk optimization, less mechanical work is needed to read small file groups. This reduces the startup time of many applications including web browsers and photos.
Unlike most other disk defragmenters, this tool can defragment locked files by running during Windows boot. Actually all files including hibernation pages and files can be defragmented there. Ultra Defrag also aims to be fast, simple, reliable, and efficient.
UltraDefrag runs on Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008 and Windows 7, including all versions of Windows 64 bit. UltraDefrag v6 can runs on Windows NT 4.0 and Windows 2000 as well. UltraDefrag cannot be used on DOS, Windows 9x, Windows NT 3.51, ReactOS and Mac OS because this operating system does not provide a defragmentation API. However, the UltraDefrag Linux port exists. This is based on NTFS-3G capabilities.
Boot Time Defragmentation: This feature provides the ability to defragment system files. Includes page files, registry sets, hiberfil.sys files, and many other files that are locked by the system or other applications when Windows is fully running.
Fast Disk Optimization: The optimizer resets all data and places it at the beginning of the drive. In many cases we have found that systems are more stable and perform much better under load, if data is placed at the beginning of the drive.
File and Single Folder Defragmentation: After UltraDefrag is installed, you have the ability to select any file or folder and delete it. This option is mostly useful, if you have just installed an application or game and want to be defragmented immediately for maximum performance.
