Comparison to other tools

Bleachbit is a master at finding and removing temporary files, while Czkawka only finds the most basic ones. So these two apps shouldn’t be compared directly or be considered as an alternative to one another.

In this comparison remember, that even if app have same features they may work different(e.g. one app may have more options to choose than other).

Big thanks to Pádraig Brady, creator of fantastic FSlint, because without his work I wouldn’t create this tool.

Thanks also to all the people who create patches for this program, make it available on other systems, create videos, articles about it etc.

Also, I really appreciate work of people that create crates on which Czkawka is based and for that I try to report bugs to make it even better.


If you are using the app, I would appreciate a donation for its further development, which can be done here.
