I just wanted to let everybody know that when you put a file on to the bookport the higher the bit rate of the original, the bigger the compressed file will be. I don't know why that surprised me, but it did. Therefore you need to be aware of that when you transfer files. Usually the file is compressed and then written back on the card. How big the final file size depends on the size of the original. The difference in size can be huge. I just wanted everybody to know that, since it came as a surprise to me. Kurt
