e4defrag vs Puran Defrag

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.

Puran Defrag is a free Windows utility for defragmenting files and optimizing hard disk drives. Its Puran Intelligent Optimizer moves frequently used files to faster disk areas, and directory consolidation can place directories in contiguous areas; that option works only on NTFS partitions. You can schedule defragmentation for startup, after intervals, or for chosen times on selected days. Boot Time Defragmentation handles system files such as the MFT, Registry, and Pagefile, or an entire drive. Low Priority Defrag uses resources when other processes are idle, so work can continue while defragmentation runs. The program can target individual files or folders, exclude them with wildcard rules, and operate through either a graphical interface or console command line. It can restart or shut down the computer after boot-time work. The listed compatible systems are Windows XP/2003/Vista/2008/7/8/10/11, including 64-bit versions; the page lists version 7.7.2, dated 07 December 2023.
