As I look at ester and timags examples, basically the way the folders are laid out is the same way I have mine the only differance being is yours is installed where mine are in exe or zip.
When I acquire content I always take a screen shot of what the content is (jpg) and I also put what model(s), figure etc it goes to and if necessary I also put other info such as if it requires other content to creat that piticular item for example Rowan for V4. To make this model it requires 3 other products to come up with model on the jpg of Rowan I put what is required whioch is ac2519 - Courageous for V4/A4, ac1957 - V4 Hooded Cloak and ac2022 - V4 Morphing Cloak and Cape. Now if I were to go to external runtimes, would I have to put all three of these together and call it , lets say "Poser-V4-Rowan". I realize that most of the content only requires 1 file, lets say V4 Hooded Cloak, but Rowan requires 3 items to creat the model. How do you know what files are required to creat Rowan? Am I getting to pickey? I hope not, I'm just curious. Cause if you just install Rowan into Poser and go to Poses, Rowan is there but nothing happens in Poser if you click on the Icon. Please bear with me, I'm trying to find out answers about Multiple RunTimes.
