Hi,
I would just like to ask a question. Excuse me if it has already been answered.
When I transfer an EPUB book from calibre to my ebook reader, three files are displayed: the epub file, the cover in jpg format and a .opf file. Are all these files necessary? I usually delete the jpg and opf files and all seem to be ok; there is no problem with the book.
Thank you!
