Hi Jarda,

yes, I also thought about that idea, only problem is that the card 
needs to be prepared on a PC, but I might be able to live with 
that....Guess it's a kind of "poor mans filesystem" :-)

I have found some information regarding direct disk access, and it 
should be perfectly possible from WinXP/2K...but the "one fixed file 
method" you describe might turn out to be easier overall....

Thanks,
Carsten
