CIRCLE WITH A DOT

@abetterjulie

Hi, technology freedom hivemind. Way back when, I downloaded my kindle library, so I was able to save my azw3 & mobi files where Amazon can't disappear them, but...
I didn't have the spoons at the time to deal with convert them to epubs, and I have no idea how to convert them now. If they can be.
Can anyone point me at a NON-techie step-by-step? I have Calibre (pre-AI edition) , but I cannot make any of the plugins work for me.
I guess can just keep reading in the app.
(boosts welcome)

#ScribesAndMakers 15 Apr: What's a smell that has featured in your work?

Petrichor.

I don't know that I've ever labeled it as such, but that earthy, unmistakeable smell of rain hitting dry earth is a favorite of mine, so it has featured in multiple stories.
