Czkawka vs Duplicate Cleaner Pro
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.
Duplicate Cleaner Pro, from UK developer DigitalVolcano Software, is a Windows utility for finding and removing duplicate files using SHA-1, SHA-256, SHA-512 hashing and byte-level comparison to guarantee true duplicates rather than false positives. It goes beyond simple duplicate detection with features like matching resized or rotated images, scanning inside zip archives, master-folder rules, and saved search profiles for repeatable cleanup workflows.
