I was recently sent a pen drive with a substantial number of books for the kindle with instructions to download the contents of the pen drive to my laptop and from there to my kindle. I think I have followed the instructions but when I look for the books on my kindle I can't find them. I've run out of ideas as to what to do next so if anyone has any idea a) what I'm talking about (I don't necessarily know what I'm talking about) and b) where the books might be hiding I'd be very grateful. Then I can send the pen drive back (honest!)!
