The Poser files will be specifically labeled for Poser and no other app. Do not install DAZ files into Poser runtimes, not necessary. For scenes and props, you usually will not find a base zip, maybe a legacy file which the label will indicate where it belongs.

Nowadays, the best way to install Poser related DAZ content is through DIM.

First, go to your DIM settings, Installation Tab and add your content runtime by clicking the + icon on the lower left, as illustrated.
