I do the old 'tried and true' method. I make a folder on the Hard drive in general, then unzip all the files there. The good ones will have directories included in the correct places, the bad ones will just sort of shotgun all over the place...;)

Once you have a load read to go (all unzipped/rar'd/whatevah...;), you open the runtime folder in Poser (I'm old-fashioned...;), shovel the Geometries from the folder where you unzipped things into the Geometries folder in Poser's runtime, same for textures, libraries, yada yada.

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