Can I store books in folders other than the My Digital Editions

I have digital books that I would like to store with other related content such as pdf, Office Files, jpegs.  Everytime I double click the digital book icon, it adds the book to Adobe Digital Editions again so that there are multiple entries in the DE library.  Is there a work around?  It is more convenient to open the book from the Explorer Folder rather than from the Adobe DE each time.
