Nested Model files?

[eluser]Matalina[/eluser]
I was more asking how to use the model after I used it. Loading and such didn't seem an issue to me, as I knew I could do that with others. I was more concerned about after I had loaded. Just making sure I didn't have to include the directory, but then again thinking about it now it seems silly cause it's the class being used not the actual file.

But Thanks for the replies they were helpful.
