Hello, Could be wrong, but I believe that a 4 gb card is the most you can use.

I'm thinking of buying either a 4 GB or an 8 GB card, and while I can use either of these in my computer, if the larger capacities don't play well with Bookport, I can save my money. I was also wondering if there was a way for the bookport to tell you how much free space you have left on a card? Thanks. ~Ann
