Is it possible to delete books of a selected format only if another format exists? I have many epub that have been converted to mobi for Kindle, but many that have not been converted. I'd like to delete only the epubs that have a mobi version.

Or maybe there is a way to convert all epubs that have not yet been converted to mobi.

Or am I a lazy, disorganized mofo, asking software to do something I should have had the brains to do before I obsessively accumulated too many books? Go ahead, say it, I can take it....
