It's just that I'm getting drag'n'drop events from the filesystem, and
data flavour from the Win32 desktop uses drive: semantics :-( I'm
using the UNC stuff everywhere internally, but I need to convert what
passed by the 'drop' event.

I'll look into the fileroots idea - it may be useful :-) The "net use" 
seems to give me what I want, but it's a bit inelegant ... I'd prefer 
a java-only approach if it were available. I'm just like that :-)
