Disk SpeedUp vs e4defrag

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.

e4defrag is a Linux utility for defragmenting extent-based files on ext4 filesystems. It accepts an individual file, a directory and its files, or a device mounted as ext4. The utility aims to place targeted data in more contiguous blocks, which the manual says can improve file access speed. Its -c option reports current and ideal fragmentation counts and a fragmentation score without making changes; the score appears only when the check runs as root. With -v, it prints error messages and each file’s fragmentation count before and after defragmentation. e4defrag checks for ext4 and reports an error for other filesystem types. It does not support swap files, files in lost+found, or files allocated in indirect blocks. A target device or mount point excludes files belonging to another device’s mount point, and fragmented or insufficient free space can prevent improvement. The manual says it is safe to run while another application uses a file, though shared memory and disk bandwidth can slow both. It is free at free.
