Disk SpeedUp
What it is
Disk SpeedUp is a free Windows utility for analyzing, defragmenting, and optimizing disks or selected files and folders. Its interactive drive map displays fragmentation results. Defragmentation modes can optimize placement for less frequently accessed files or prioritize frequently used files. Users can schedule a run by choosing its action, frequency, time, and drives, and enable boot-time defragmentation for system files such as page files, registry hives, and hiberfil.sys. The utility also 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 from defragmentation, enable Disk Defrag in the Windows Explorer context menu through Glary Utilities settings, and set the computer to shut down after a run. The download page lists version 6.0.1.17. Disk SpeedUp has a free plan and no free trial.
