Betty: Usually, the disc is full means one of two things: either there's not enough room on the Compact Flash Card, or your hard drive on your PC is nearly full and there is not enough sufficient room on the hard drive to complete the transfer process. The files are temporarily placed on the hard drive, before they are placed on the compact flash card and Book Port. You might try deleting your temporary internet files and anything else you don't need on your PC and try the transfer again. If that doesn't help, then I would reformat the compact flash.

I have downloaded the latest firmware and software updates at the prompting of the bookport transfer software. I have a books folder and I transferred 6 daisy books without incident. I also put a few etext books on and then read some daisy books and deleted them. Now, when I try to add more daisy books, I get a prompt that says .mp3 disk is full. When I check in My Computer in the properties, I have more than 2 gigs of space left on my flash card. Is the only solution to reformat the card and retransfer? Do I need to not delete files after I have read them? Betty Nobel
