Czkawka (tch•kav•ka (IPA: [ˈʧ̑kafka]), "hiccup" in Polish) is a simple, fast and free app to remove unnecessary files from your computer.
Krokiet ((IPA: [ˈkrɔcɛt]), "croquet" in Polish) same as above, but uses Slint frontend.
Features
Written in memory-safe Rust
Amazingly fast - due to using more or less advanced algorithms and multithreading
Free, Open Source without ads
Multiplatform - works on Linux, Windows, macOS, FreeBSD and many more
Cache support - second and further scans should be much faster than the first one
CLI frontend - for easy automation
GUI frontend - uses GTK 4 or Slint frameworks
No spying - Czkawka does not have access to the Internet, nor does it collect any user information or statistics
Multilingual - support multiple languages like Polish, English or Italian
Multiple tools to use:
Duplicates - Finds duplicates based on file name, size or hash
Empty Folders - Finds empty folders with the help of an advanced algorithm
Big Files - Finds the provided number of the biggest files in given location
Empty Files - Looks for empty files across the drive
Temporary Files - Finds temporary files
Similar Images - Finds images which are not exactly the same (different resolution, watermarks)
Similar Videos - Looks for visually similar videos
Same Music - Searches for similar music by tags or by reading content and comparing it
