I've only had my BookPort a few weeks and am getting ready to replace the original CF card with a 1 Gig card. If I install the 1 Gig card and then hook the BookPort up to my PC, will the transfer tool software see that the users manual is missing and install one automatically or do I have to somehow tell it to do so? I'm mostly interested in listening to mp3 files on the BookPort. Will I be giving up very much by just using Windows Explorer to copy files to the BP rather than using the transfer tool? Thanks Richard Ehrler
