Compared on disk defragmentation software

Purpose: Defraginator is a cross-platform desktop app for defragmenting `.bin` ROM and firmware images on SD cards and other removable media.
File selection: It scans for `.bin` files that match enabled target sizes of 256 KB, 512 KB, 1024 KB, or 2048 KB.
Workflow: The app detects mounted removable volumes, recursively scans matching files, checks their physical cluster layout, and relocates fragmented files into contiguous free space.
Windows support: On Windows, it uses filesystem controls to find contiguous free clusters and move file clusters in place; moving clusters requires administrator rights.
Linux and macOS support: On Linux and macOS, it rewrites files and verifies their physical extent layout; Linux’s FIBMAP fallback requires root, while the listed macOS operations run as a normal user.
Safety: The README says the original file is restored if contiguous placement fails on Linux or macOS, and success is reported only after physical contiguity is verified.
Operating caution: Users are told not to remove the card while defragmentation is in progress.
Space requirement: Defragmentation requires a contiguous free gap at least as large as the file; the app reports free space and, on Windows, the largest contiguous free block.
Runtime requirement: The repository lists the .NET 10 SDK as a requirement and provides build-and-run commands.
License: The repository identifies the project as GPL-3.0 licensed.
