Disk SpeedUp
glarysoft.com
What it is
Disk SpeedUp is a Windows utility for analyzing and defragmenting drives, as well as optimizing individual files and folders. Its interactive drive map displays fragmentation results. Defragmentation modes can optimize placement for less frequently accessed files or prioritize frequently used ones. Scheduling lets users choose an action, frequency, time, and drives. It can also defragment system files at boot, including page files, registry hives, and hiberfil.sys. The utility offers SSD optimization settings, but its knowledge base says defragmenting SSDs is not recommended because it may reduce their lifespan. Supported file systems are FAT 16/32 and NTFS. Users can exclude files and folders, enable Disk Defrag in the Windows Explorer context menu through Glary Utilities settings, and set the computer to shut down after defragmentation. Glarysoft says the product is designed to avoid damage to drives or stored data and typically responds to technical questions and bug reports within one or two business days. It is listed as freeware at free, with no free trial. The download page lists version 6.0.1.17.
