Beth: It is best to organize your files into folders, since you can only have a = few files in the root of the card. You might try deleting the files from = the card, creating a folder or two, switching to one of your folders and = resending the files. Let me know if this doesn't work.

I downloaded a number of brf files to it, and when I try to play many of them, Bookport says something about an application or data file and gives = me an error message. It says it can't open the file. Why might this be? Did I do something wrong? Thanks, Beth
