To get your extra content here what you need to do is point Poser 6 to the Runtime folders with your other content. To do this, you need to open the Library and point it to the base folders (you'll see a folder named "Downloads" and another named "Poser 6"). When you do this, you'll see a check mark and a + button on the library. Hit the + button (its tool tip reads "Add Runtime"). This will open a standard operating system browse window. Simply point it to the Runtime folder you wish to add and voila. You now have another Runtime library set. As for the DAZ Studio content, some of the DAZ meshes are not compatible with Poser so keep that in mind if they don't work.
