Ok, so here is the scenario. I have hundreds of potential mp3's I want to send to the bookport, and only so much space on the card. I would love it if I could select a bunch of files and know right away how much space they will take up so I can decide and prioritize which files to send in which batch. I know I can easily check the space left on the card by reading the status line in the transfer software, but this is different. I want to pick my ten files or 20 or whatever and know at a glance they will take up 320 mb of space on the card so I can then decide what to eliminate etc. Is it just me or would other folks benefit from this type of information and could such a utility be added easily? Thanks all. Don Barrett
