u3: where to store data?

[Malte Brill]

Hi all,

I thought I´ll give the u3 thingy a shot today, so I got me a small u3 
drive. Now I wonder: Where should my app store its data? Where would 
preferences usually go? I already looked at the globals and checked the 
paths in there. I recall vaguely that I have seen a post on this a while 
back, but a search comes up with zilch. Any hints welcome.

All the best,

Malte
