There is no limit anymore, however, remember that if you use any of the Pause Compression features, that will make a difference.

Anyhow, I have an MP3 file that's 839 meg (880,398,964 bytes) in size. However, when I tell Bookport Transfer to send it to my bp which has 1.9 gig free on the card, I receive this message: FFMP3 The source file is too large. The file will be truncated at 4GB. OK What's going on? I had just reformatted the card in the BP, too. The entire file does seem to have been transferred, so I haven't a clue what this message meant. -- Walt Smith - Clearwater, FL walt@xxxxxxxxxx
