Would anyone happen to know what a azw4 file is? I've bought lots of books from Amazon but never came across this before, I usually like to convert to epub but Calibre fails every time.
Does anyone know how to convert?

Thanks.

Basically, azw4 is a PDF wrapped in Amazon's own package. More or less the same as azw3 and epub.

Ok thanks, I will give it another run through calibre. I may be able to zip it and extract as a cbr file.
