When I go to install the V4 Elite series, do I need to make a separate "DAZ V4" folder for all the different Elite girls, or will it do that automatically?

Also, do I need to make a new dummy Poser.exe file for each different kind of content or Poser model? Iow, one for V4, one for A4, then S4, then hair, then props, then lights, then etc, etc, etc?

Do I need to install to the folders I already manually made for hair, props, hands, camera, library, etc, etc?

OR,

Does the installer end up pouring everything into one BIG runtime folder, face, lights, props, everything?

If I can just get everything installed correctly, then I think I can use the many tutorial videos for everything else.  Maybe.  But then again, if the tutorial videos answered everything, then there wouldn't be so many of us here on this forum. Asking everything from newbie questions like me all the way up to the rocket science questions like others here.
