Sorry if this has already been answered, I wasn't able to find the answer in a forum search...
When I have multiple versions of a book, ex. (pdf, mobi, epub) and transfer to device, I noticed that the format being transferred is pdf.
pdf files are
not ideal for reading pleasure on my Kindle KB.
How do I make certain that calibre knows to send the mobi or epub version over the pdf?
-OR-
If that isn't possible, how do I delete only the pdf version from my calibre library?
TIA for any help you experts can provide!
