okay, they go into the folder too and I assume i check the box "load loose files"?
Load loose files is kind of tricky. I myself don't use it. From what I understand its for when a modder doesn't properly path his/her textures correctly. The game then hunts down any "loose" files and puts them into the game.
I'd recommend keeping it off unless a mod tells you to turn it on. If you encounter any odd pink graphics, and have tried turning off and back on archive invalidation invalidated, then try load loose files. Also, if you use fomm it has its own invalidation(which is all you need for that), under tools. Make sure its clicked. Just figured I'd preemptively strike on the invalidation issue, since it tends to spring up early for new mod users
