Sometimes people make "free stuff" because they want to give back to the community. Sometimes these generous people don't actually understand all the nuances of the file structure and how to make them install seamlessly. For someone who understands it, it is simple. For a newbie, it is a nightmare and I do speak from experience. I was lucky that someone actually took the time to send me a screen shot of the naming conventions and all the file making utilities available. Maybe we should have a "preferred spec sheet" available for people making this art available to us in the free section. A list with things like "file maker and P3DOExplorer, how to set up a "runtime" folder. Even how to prepare a zip file. It was the screen shot of that stuff that helped me through the confusion. If you find someone who doesn't understand it you could graciously send them the link with the spec sheet.
