Hello.
I convert all my ebooks in epub, and what I would like is a button where I can delete the original file and save on disk space.
I buy all my books in epub format: from all romance, coffee shop romance, smashwords, blushing, and the other file format from amazon (I don't really care about that coz I've got Kindle desktop), but mostly I got them in other formats from my forums, and they are like a damn anvil in my drive.

So maybe, pleeease, Kovid's team could look onto that?
Thank You
