Czkawka is a multiplatform Rust-based app for finding duplicates, empty folders, similar images, and other unnecessary files using tools like big files finder, broken files detector, and Exif remover.

It features Krokiet as the new Slint GUI frontend, Czkawka as the older GTK4 version with bugfixes, and Cedinia as an experimental Android frontend. The open-source tool supports Linux, Windows, macOS, FreeBSD, ARM, RISC-V, and Android with CLI, cache, and multithreading for speed.
