Most downloads include Readme files, and usually, those files will tell you where to put things to make them work, so that's the first place to look. It can be very hard figuring out all this stuff, but once you start to learn how all these files relate to each other, you'll find it much easier. The Poser manual is limited, but it is worth a read-through. I must say, though, I went through all the tutorials step by step when I first bought my seconhand copy of Poser 2, but I didn't learn as much as I did from online tutorials and helpful people. Don't expect to be completely facile with the program right out of the box-- the program is deceptively easy to use, while there are a wealth of subtle and not so easy things you can do with it to get truly lovely results. Do check the tutorials here. There are many that cover precisely the areas that the Poser manual fails to cover at all or in sufficient detail. And do stick around!
