Essential System Tools: Czkawka – data cleaner

This is the latest in our series of articles highlighting essential system tools. These are small, indispensable utilities, useful for system administrators as well as regular users of Linux based systems. The series examines both graphical and text based open source utilities. For details of all tools in this series, please check the table in the Summary section.

Even though the cost of storage per GB continues to fall, it’s common for users to need to find and remove duplicates files. The process of finding and removing duplicates is time-consuming. Fortunately, there are a number of tools that are designed to remove the laborious nature of finding duplicates. We recommend fdupes, an excellent command-line tool. We know that many users prefer software with a graphical user interface.

Czkawka is an app that finds duplicate files, big files, empty files, similar images, and much more. Czkawka is free and open source software.

Installation

The project provides binaries for both its graphical user interface and command line interface.

There’s also an AppImage available. AppImage is a universal software format for distributing portable software on Linux without needing superuser permissions to install the application. AppImage doesn’t really install software. It’s a compressed image with all the dependencies and libraries needed to run the desired software.

There’s the full source code available if you prefer manually compiling.

And the project also provides binaries for Windows and macOS.
