Another quick cheat: in the main Poser runtime there is a folder labeled Downloads. CL added it when they added the content room in P5. It is the folder that if you bought and downloaded from the content room from CP, the content would install to. It has all the folders set up in standard Poser runtime format. By default the folders are empty. You can make a copy of the Downloads folder and paste it wherever you want or wherever your other external runtimes live. Change the Downloads label to whatever name you want. You have a standard runtime folder set up without having to make one.
