I read most frequently asked questions and all and this question doesn't come up. I also read somewhere about something on unpacking the BSA files? Where are those if anyone has an answer?

I'm trying to locate the character files for modding the animations. I have many ideas I've written down and illustrated and I plan to be working through Cinema 4D and many other applications, but

right now I desperately need the character files!

Creature .NIFs are all in Meshes\Actors (save for those in Meshes\Critters).

To unpack BSAs, you just need a utility such as http://sourceforge.net/projects/fomm/ (there are others) and you extract to Skyrim\Data as BSAs have the same folder structure.

Thank you! Anything I can do for you just PM me

Actually I said thank you too early, I had to be somewhere before I could actually check and there are no .BSA files anywhere on my system.

They should be in Skyrim\Data, if they are not then you wouldn't even be able to play the game.
