FS panic FS error playing unfiltered files not supported I have: * Re-formatted CF. * Tried different CF. * Re-installing software. * _Not_ too many files in route - I learned this 25 years ago as a computer scientist! :-) In fact, what I'm sending is directories (if you prefer folders) with sub-directories and files. * Tried re-booting and leaving out batteries. I'm using XP Pro. Also for some reason BP software doesn't like some of my rtf files!? The problem seems to happen most commonly with mp3 files. I have a folder called music with sub-folders for each album. So it would be \music\artist\tracks The problem doesn't seem to happen quite so much with the 2gb CF cards I have. On this group I've been told that BP officially takes up to 4gb? But I think the UK retailer claimed it officially takes up to 2gb. Which is right? Is there a remote chance there is something wrong with my CF cards (I have several 4gb) from BP's viewpoint? They are OK in other devices. And yes, I have formatted them in BP more times than I can count. BP seems to have caused me nothing but problems. When it works, which I think is only on 2 occasions, it is absolutely brilliant! But more often than not, it doesn't work and causes great frustration! Oh, is that lovely sounding leather case available in the UK? Cheers Fil
