I read a lot of books and keep downloading books that I've already read. It would be really nice if Digital Editions would keep a simple database of books that you have downloaded (to a particular account). I used to be able to find most books in C:/documents/my digital editions/annotations, but that somehow got messed up and also no longer seems to have the books I've downloaded.
I'm using Digitasl Editions version 3.0.1 because newer versions do not work with my old Nook
All eBooks which have in Digital Edtion found you under My Documents > My Digital Edition. You has no database for this because digital edition its only a simple program for open eBooks not for creates database.
