About:
fclones is a high-performance duplicate file finder written in Rust that uses efficient hashing algorithms to quickly identify identical files. It can hard-link or symlink duplicates to save disk space without data loss. The tool offers parallel processing capabilities for scanning large filesystems rapidly.
Key Features:
  • Parallel processing for fast scanning
  • Multiple hash algorithms (xxh3, blake3, etc.)
  • Hard-link and symlink replacement options
  • Dry-run mode for safe testing
  • Cross-platform support
Use Cases:
  • Cleaning up duplicate files in large media libraries
  • Deduplicating backup directories
  • Freeing up disk space on development systems
  • Identifying duplicate downloads or documents
Alternatives:
  • fdupes – fclones is significantly faster and more feature-rich
  • rmlint – fclones offers better performance and simpler CLI interface
