Defragger vs Defraginator

Defragger is a graphical Linux tool for examining and defragmenting filesystems, with a map showing file, free-space, and metadata allocation. Its analysis identifies fragmentation and displays filesystem blocks in an adaptive map. The project supports online defragmentation of ext4 and offline defragmentation and compaction of FAT16 and FAT32. FAT12 and exFAT can be analyzed, but not modified. A command-line interface can list, analyze, defragment, and compact volumes. The interface and command-line program run without elevated privileges; operations that need them use a PolicyKit-authorized helper over D-Bus. The stated environment is Linux with Qt 6 and KDE Kirigami; privileged mode also requires systemd, PolicyKit, and an active graphical PolicyKit agent. For ext4, Defragger uses Linux filesystem ioctls directly rather than calling e4defrag or filefrag. The project labels the software alpha, recommends backing up important data, and says ext4 has received the most testing. FAT write support is newer, so it recommends beginning with disposable or fully backed-up volumes. The software is dual-licensed under MIT or Apache License 2.0.

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.
