Czkawka is a simple, fast and easy to use app to remove unnecessary files from your computer.
- 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 and macOS
- Cache support - second and further scans should be a lot of faster than the first
- CLI frontend - for easy automation
- GUI frontend - uses modern GTK 3 and looks similar to FSlint
- Rich search option - allows setting absolute included and excluded directories, set of allowed file extensions
or excluded items with the
- Multiple tools to use:
- Duplicates - Finds duplicates basing on file name, size, hash, first 1 MB of 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)
- Zeroed Files - Finds files which are filled with zeros (usually corrupted)
- Same Music - Searches for music with same artist, album etc.
- Invalid Symbolic Links - Shows symbolic links which points to non-existent files/directories
- Broken Files - Finds files with an invalid extension or that are corrupted
You can find an instruction on how to use Czkawka here.
If you are using Windows or Mac binaries, there is no specific requirements.
Same with Appimage on Linux (except having system 18.04+ or similar).
Although, compiled GUI binaries on Linux or compiling it on your own OS requires you to install these packages:
sudo apt install cargo libgtk-3-dev
sudo yum install gtk3-devel glib2-devel
Ready-to-go executables are available here.
If the app does not run when clicking at a launcher, run it through a terminal.
You don't need to have any additional libraries for CLI Czkawka
For Czkawka GUI you are required to have at least
GTK 3.22 and also
Alsa installed (for finding broken music
files). It should be installed by default on all the most popular distros.
czkawka_gui.exe which is extracted from the
windows_czkawka_gui.zip zip file needs to be in the same
file as the rest. If you want to move and open the executable somewhere else, you need to install the
runtime from here.
Currently you need to manually install
GTK 3 libraries, because they are dynamically loaded from the OS (we need
help in using static linking). Installation in the terminal:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" brew install gtk+3
After that, go to the location where you installed this and add the
chmod +x mac_czkawka_gui
Execute in the same folder with:
Appimage files are available in release page - Github releases There is a problem with this currently, as it doesn't allow you to open two images/files at once.
The easiest method to install Czkawka is using the
cargo command. For compiling it, you need to get all the
requirements from the compilation section
cargo install czkawka_gui cargo install czkawka_cli
You can update the package with the same command.
Snaps also are available, but there is no access to external drives.
sudo snap install czkawka
The Snap store entry can be found here.
Fresh builds are created for every commit, but they may be a little unstable, although that happenes very rarely because I don't push untested code.
I tried to set up it, but I'm having problems described in this issue.
Czkawka is also available in Arch Linux's AUR from which it can be easily installed.
yay -Syu czkawka-git
This is unofficial package, so new versions will not be always available.
Artifacts from each commit can be downloaded here
The compilation section is generally not recommended, because you have multiple better sources of this app than compiling it yourself.

If you only want the terminal version without a GUI, just skip all lines about

You need to install Homebrew and GTK Libraries
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" brew install rust gtk+3
Will be avaible in the future
- Download the source
git clone https://github.com/qarmin/czkawka.git cd czkawka
- Run GTK GUI
cargo run --bin czkawka_gui
For Linux-to-Windows cross-building instruction look at the CI.
- Run CLI (this will print help with a lot of examples)
cargo run --bin czkawka_cli
Since Czkawka is written in Rust and it aims to be a faster alternative to FSlint (which written in Python), we need to compare the speed of these tools.
I tested it on a 256 GB SSD and a i7-4770 CPU.
I prepared a directory and performed a test without any folder exceptions (I removed all directories from FSlint and Czkawka from other tabs than Include Directory) which contained 229 868 files, took 203.7 GB and had 13 708 duplicate files in 9117 groups which took 7.90 GB.
Minimum file size to check I set to 1 KB on all programs.
|FSlint 2.4.7 (Second Run)||86s|
|Czkawka 1.4.0 (Second Run)||12s|
|DupeGuru 4.0.4 (Second Run)||28s|
I used Mprof for checking memory usage FSlint and DupeGuru, for Czkawka I used Heaptrack. To not get a crash from DupeGuru I checked a smaller directory with 217 986 files and 41 883 folders.
|App||Idle Ram||Max Operational Ram Usage||Stabilized after search|
|FSlint 2.4.7||62 MB||84 MB||84 MB|
|Czkawka 1.4.0||9 MB||66 MB||32 MB|
|DupeGuru 4.0.4||80 MB||210 MB||155 MB|
Similar images which check 332 files which took 1.7 GB
Similar images which check 1421 image files which took 110.1 MB
So there is still is a lot of room for improvements.

Contributions to this repository are welcome.
You can help by creating a:
- Bug report - memory leaks, unexpected behavior, crashes
- Feature proposals - proposal to change/add/delete some features
- Pull Requests - implementing a new feature yourself or fixing bugs, but you have to pay attention to code quality. If the change is bigger, then it's a good idea to open a new issue to discuss changes.
- Documentation - There is an instruction which you can improve.
The code should be clean and well formatted (Clippy and fmt are required in each PR).
Czkawka is a Polish word which means hiccup.
I chose this name because I wanted to hear people speaking other languages pronounce it.
This name is not as bad as it seems, because I was also thinking about using words like żółć, gżegżółka or żołądź, but I gave up on these ideas because they contained Polish characters, which would cause difficulty in searching for the project.
At the beginning of the program creation, if the response concerning the name was unanimously negative, I prepared myself for a possible change of the name of the program, and the opinions were extremely mixed.
