Along these lines... I am an OLD Poser user... I skipped the growing pains of 8, 9, 10, 11, and 12.. so my runtimes are kind of a mess and Poser 13 just laughs at me when trying to import them.   So I will need to sort out every one with the proper folders now. 

Also, do people use the Collections and Other folders for anything?

Thanks a bunch in advance!
