How do I actually put the model stuff on here into Blender?

[Sleepless]

I downloaded a Pikachu model, and it has a bunch of files in it, like .fbx and .smd and .DAE files, along with some png images. As a complete noobie to all of this, how to I actually put all of this into Blender? Help appreciated.

Starting with a new scene I just import Collada (the DAE file) and it works for me.

What Kiromits said. Blender doesn't open stuff, it imports them. That being said, you can extend it's potential with python scripts.
