About:
Rdfind is a command-line utility that identifies duplicate files by comparing their content checksums, regardless of filenames or directory structures. It provides options to create hard links, symbolic links, or delete redundant copies to reclaim disk space. This tool is particularly effective for cleaning up media libraries, backups, and synchronized folders.
Key Features:
  • Content-based deduplication using checksums
  • Supports hard links, symlinks, and file deletion
  • Handles large filesystems efficiently
  • Cross-platform (Linux, macOS, Windows)
Use Cases:
  • Cleaning up duplicate photos and videos in media libraries
  • Reducing storage usage in backup directories
  • Managing duplicate files in synced cloud storage folders
Alternatives:
  • fdupes – fdupes is faster for small datasets but lacks rdfind's advanced linking options
  • dupeGuru – dupeGuru offers a GUI interface but is less suited for automated command-line workflows
