Works great and felt very intuitive i do not know enough to give a more technical review but what i can say is that so far it seems to have multiple ways of finding duplicate files and it works very well in my experience. as a windows surviver i admit this feels comfortable to use and yes i know the command line terminal and yes i do love using the command line however this is just a no nonsense program in my experience and its wonderful.

Good piece of software, but hard to find in the repos, if you do not speak Czech or what! Developers should think about a more related name. Every time I want to install it I have to search my old docs first to find the name.

I highly recommend it for file cleanup. Czkawka is a very close re-implementation of Fslint. Fslint has been one of my often used utilities to keep my storage clean but it disappeared starting with Mint 20.x so I'm very glad to have discovered this package. In fslint one right clicked on a directory to get options for selecting similar directories. Czkawka uses a select button with regex support. It quickly finds dups, selects targeted files/folder and deletes as requested.
