I believe (and I could be wrong) that the file size is is somewhat smaller when compression is applied. I must echo what a tremendous job APH has done. I have owned a bookport for a bit over a year now, and so many new features have been added and old ones refined in this short space of time that one can truly appreciate the work that has gone into this device. -----Original Message----- From: bookport-bounce@xxxxxxxxxxxxx [mailto:bookport-bounce@xxxxxxxxxxxxx] On Behalf Of Donna Slater Sent: Friday, August 13, 2004 2:45 AM To: bookport@xxxxxxxxxxxxx Subject: [bookport] Audio file questions Sorry about my last message, I inadvertently sent it before I finished writing. I would like to know if the compression on the file has any effect on the file size? Also, if I have a file which is too large for my cf card, can I split it in some way (the file being an mp3)? Thanks to all at Aph for such a superb product. I've had a bookport since they were launched and the improvements have been incredible. Best wishes Donna Slater.
