Hi, I thought I understood how to do this so that Penfriend readers could all be loaded with WAV files recorded in a studio, and used by visitors to an attraction to hear the same info every time they hit a particular label. The file structure of the Penfriend looks very complicated, and while I'm pretty sure they are somewhere in the Rec directory, I need help to understand where the files go. Another problem is that I don't seem to be able to play the WAV files on any of the players installed on my laptop, which is odd. Please could someone enlighten me so that the project I'm trying to assist won't run into an unnecessary difficulty. Thanks, Richard Godfrey-McKay Telephone: 01738-445 880 Mobile: 07791 452 593
