Quote - I don't run across many stray files unless its say textures but what I find is stuff either comes as a runtime in a zip file or the stuff from Daz is exes which you just point it right to your runtime. In the zips I just drag and drop and overwrite my real runtime I use with the one in the zip and it adds everything nice and neat and you don't have to worry about it deleting. Its hard to get use to doing that till you do it awhile then it comes easy and everything is where it should be and should be available to you in poser. I find sometimes I have to explore those zipped runtimes and get folder names to search for to help me find it in the poser search engine.  

 

To clarify on the Daz3d install exes, I think its you just point to the folder your runtime is in i.e. Poser Pro 2012 and not actually in or the root of the runtime folder itself.
