About:
Czkawka is a fast and efficient duplicate file finder that identifies redundant files using multiple methods like file size, hash, and filename comparison. It supports various file types including images, videos, music, and documents, and offers both a CLI and a modern GTK GUI. The tool helps users reclaim disk space by safely removing duplicates while providing options to hardlink or symlink files instead of deleting them.
Key Features:
  • Multi-platform support (Linux, Windows, macOS)
  • Multiple comparison modes (size, hash, name, etc.)
  • GUI and CLI interfaces available
  • Supports image, video, music, and document analysis
  • Safe operations with hardlink/symlink options
Use Cases:
  • Cleaning up duplicate photos and media files
  • Freeing up disk space on large storage drives
  • Organizing scattered document backups
  • Finding duplicate downloads folder contents
Alternatives:
  • fdupes – Czkawka provides GUI and more comparison modes
  • dupeGuru – Czkawka is generally faster and more modern
  • rmlint – Czkawka offers easier GUI interface for beginners
