There might be a 'recurse subdirectories' preference (it was in Pkzip..;) Check Greylight's site, and possibly Space Storie (Anthony Appleyard) for some Poser 3 stuff..Poser 3 sets up a large number of folders..I don't have a copy here, or I could tell you, but depending on what it is, there's hair, figure, etc. kind of directories.
Also drop by Ron Knights' site for beginning tutorials, they can be right helpful (I've got a thread in the 3d links forum here with a file with many Poser tuts..but I'm still culling the dead sites out of it..most of the above-mentioned are there).

I wish I'd said that.. The Staircase Wit
