You're welcome.

Actually, I don't use this method myself, because I don't trust all vendors to create the required folder structure in the archive for expanding directly into a Poser Library. I think I may also have seen the problem where it creates a new Runtime folder (e.g. Runtime-1) instead of merging into the target folder. But that may have been with a prior version of Stuffit Expander.

I always expand product archives (zip or sit files) into a separate /Runtime folder, save this to my external backup drive, then use the dittoGui utility to merge the content into one of my Poser Libraries.
