Hi, Stacy, Your VN will support only the BRF format. I would personally recommend that you wait until you can afford a five gig hard drive before you buy additional storage capacity. I think they run around $150 now, but someone else may be able to confirm that and tell you where to purchase them online. The reason I suggest you buy the five gig drive is that you'll have to make one slightly major investment as opposed to several flash cards, and you won't need a flash card reader.
