I like to create and keep an empty runtime for quick (it's actually not that quick) creation of multiple external runtimes. So I drag a copy of the empty Runtime to a folder Aiko 3, another to Aiko 4 (etc). One caveat, this file structure is Poser specific. Creating runtimes for Daz Dson imported content is slightly different. That would be covered in another thread if you post the question.

The dust settled, thinking "what a fine home, at least for now" not realizing that doom would soon be coming in the form of a vacuum cleaner.
