Defraginator vs Disk SpeedUp

Defraginator is a desktop utility for making selected ROM and firmware `.bin` images contiguous on removable storage. It detects mounted volumes that appear to be removable, scans them recursively, and checks matching files’ physical layout. You can enable or disable target sizes of 256 KB, 512 KB, 1024 KB, and 2048 KB; files outside those sizes are not in scope. The app needs a single free gap at least as large as the file. It reports available free space and, on Windows, the largest contiguous block; on Linux and macOS, that largest-block figure is unknown. Windows moves clusters in place and requires administrator rights. Linux and macOS rewrite files into newly allocated space and check their physical extents; the Linux FIBMAP fallback requires root, while the listed macOS operations run as a normal user. The project says it restores the original after an unsuccessful rewrite and reports success only after verifying contiguity. Keep the card connected during work. Defraginator is free and GPL-3.0 licensed; building it requires the .NET 10 SDK.

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.
