Clean Your Storage Faster with Czkawka
Find duplicate files, similar photos, empty folders and space-hungry files. Learn a careful Windows workflow that protects the originals you want to keep.
Current project release: 12.0.2 · Krokiet is the maintained graphical interface. Always check the source and file before running.

Powerful features, careful decisions
Use the right detector for your task. A result is a candidate to review—not automatic permission to delete a file.

Built for finding files you can review
Czkawka is an open-source tool written primarily in Rust. Its scanners locate exact duplicates, similar media, empty files, large files and other candidates across folders that you select.
As of release 12.0.2, Krokiet is the frontend maintained by the project. Older Czkawka GTK builds remain a legacy option. We explain both so Windows users know which executable they are choosing.
