What is it?

Krokiet and Czkawka are file cleanup applications that scan a computer for unnecessary files. Krokiet is the newer Slint-based GUI, while Czkawka is the older GTK 4 frontend whose final release is 12.0. Both share the same core library, czkawka_core, which also has a CLI frontend for scripting. Cedinia is a touch-friendly Android frontend built on the same core.

The tools cover duplicate files (by name, size or hash), empty files and folders, big files, temporary files, invalid symbolic links, broken or corrupted files, and files whose extension does not match their content. Similar-content tools find visually similar images and videos and music with matching tags or audio content. Additional utilities remove Exif metadata and optimize videos by cropping static parts or converting formats.

The project is written in Rust, runs on Linux, Windows, macOS, FreeBSD and Android, and caches results so repeated scans are faster. It does not connect to the internet or collect user data.
