Thanks for the responses Lunch, & Iron, I tried the card reader, another PC, the R09 itself, nothing will recognize the file. I can open the card to view the files on it, and there is the successfully transferred wav, and the .wcv file in that damn icon that you know you won't be able to open. It also is hidden. Tried changing file name, and extension, won't let me. Pig I went to the FAT link you provided, and honestly, it looks a bit over my head, at least without really doing some reading and I don't have time now. It looks like a deep technical pit that I could spend hours fiddling around and still come up empty, (and frustrated) Is there any way to "check" a flash card to see if it's been damaged? I'd hate to have a repeat, I've got 5 shows this month! Is there a more reliable card? I upgraded my R09 to the most current version to see if that helps. Great Fun! Thanks again guys.
