Czkawka vs dupeGuru
Side-by-side comparison of features, pricing, ratings, and alternatives.
Czkawka is a free, open-source, cross-platform tool that finds duplicate files using content hashing rather than filenames or sizes alone, and goes further by detecting visually similar images, similar audio, broken or corrupted files, empty folders, and unusually large files. Built in Rust, it uses CPU-efficient multithreading to scan large drives quickly. It offers both a GUI, via the newer Krokiet frontend, and a command-line interface for automation, runs entirely offline with no telemetry, and supports batch actions to move, delete, or symlink duplicates once reviewed.
dupeGuru is a free, open-source duplicate file finder for Windows, macOS, and Linux. It scans folders by filename or file content to identify exact duplicates, and includes a dedicated Picture mode that finds visually similar images even when they differ in resolution or format. A Music mode adds tag- and metadata-aware scanning for audio libraries, while a customizable matching engine, reference-folder logic, and filtering tools let users review results carefully before choosing to delete, move, or copy the duplicates it finds.
