you need the "Guide to Poser file placement " which will tell you where the poser stuff should go.

letse if I can find it in the tuts here :-..... http://www.renderosity.com/mod/tutorial/index.php?tutorial_id=1275

try that for a start.

obj, 3ds that are not part of a poser item can go anywhere because you will import them and then save within poser as a prop.
