Disk SpeedUp is a free Windows utility for analyzing disks, defragmenting them, and optimizing selected files or folders. An interactive drive map displays fragmentation results. Users can choose modes for placing less frequently accessed files or prioritizing frequently used files, then schedule an action by selecting its type, frequency, time, and drives. It can also defragment system files at boot, including page files, registry hives, and hiberfil.sys. SSD optimization settings are available, though the knowledge base says defragmenting an SSD is not recommended because it may shorten its lifespan. Supported file systems are FAT 16/32 and NTFS. Users can exclude files and folders, enable the Windows Explorer context-menu option through Glary Utilities settings, and configure an automatic shutdown after defragmentation. The download page lists version 6.0.1.17. Glarysoft says it usually responds to technical questions and bug reports within one or two business days.
