Czkawka vs Wise Duplicate Finder
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.
Wise Duplicate Finder, from WiseCleaner, is a Windows utility that scans local disks for duplicate documents, photos, videos, and music, letting users compare files by name and size, partial content, or full content for varying levels of match precision. It includes a Restore Center to recover files deleted by mistake and automatically flags empty (0-byte) files during scans.
