About fclones
fclones is a command-line utility that identifies groups of identical files and removes unneeded copies. It supports filtering by path, name pattern, file size and recursion depth, accepts file lists piped from standard input, and outputs results as text, CSV or JSON.
Lists of duplicates can be inspected and modified before removal, and a --dry-run option shows planned file-system changes. It is available on multiple operating systems but works best on Linux, and copy-on-write reflink deduplication is not supported on Windows.

- Identifies groups of identical files via command line
- Filters by size, glob, regex, depth, symlinks and hardlinks
- Removes, moves, or replaces duplicates with soft or hard links
- Supports copy-on-write reflink deduplication on some file systems
- Outputs results as text, CSV, or JSON for further processing
- Accepts file lists piped from standard input and Unix tools
Best for: Users comfortable with the command line who need to find and clean up duplicate files, especially on Linux.
