Maybe Amazon puts some form of encryption that makes it accessible only from your account?! Not sure as I don't use it.. Have you tried browsing into the Letter/Number folders Fudgey? The books may be within them. Again not having used a Kindle, I don't know how it arranges the files on the computer. As for our Darling spouses, my wife feels the same. Five 6-foot bookcases were where she drew the line. So, I started stacking some of my books side-ways. Deceptively space saving.
