Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

dskDitto is an open-source duplicate-file finder for local filesystem paths on macOS and Linux. It suits technical users who want detailed control over how files are matched, reviewed, filtered, and handled. The application scans directories in parallel and can also search for duplicates of a single file. Results can be browsed and managed through a terminal user interface, while an experimental Raylib graphical interface provides another way to interact with the project. Its Unix-like focus makes it a more specialized choice than a general desktop cleanup utility.

Matching depth is a key strength. dskDitto supports SHA-256 and BLAKE3 content hashing for exact duplicate detection, alongside exact filename matching and fuzzy content similarity for near-duplicate files. File previews, selection automation, folder exclusions, and scan filtering help narrow the results before taking action. The available actions go beyond deletion: users can create symlinks or reflinks on supported filesystems. CSV, JSON, and plain-text exports also make the results suitable for review or further processing outside the application.

The trade-off is usability and scope. A terminal-oriented workflow will appeal to people comfortable with command-line tools, but it may require more familiarity than a visual duplicate finder. The graphical interface is experimental, so users seeking a mature GUI-first experience may prefer an alternative. dskDitto is a strong fit for macOS and Linux users who prioritize open-source software, configurable matching, automation, and filesystem-aware actions. It is less suitable for users who want a polished graphical workflow or a broader desktop-platform focus.

  • Where it doesn't
    • Terminal interface may be less approachable for general users
    • The Raylib graphical interface is experimental
    • Designed for Unix-like systems rather than broad platform coverage
