I'm very disappointed that its "Convert" does not work -- I want my money back!!! It also becomes unresponsive (hangs) when doing various things, such as .7z archives and Convert. It is slower than Keka at .7z archiving and also has fewer options. I also do not like how it requires a window showing the archive open which can take some time even when you only care about drag & drop compression & extraction. I recommend Keka, which is free, instead.
