Exporting 3D models with animation from Max to Unity?

Hi,

I'm having trouble exporting animated characters from 3ds max to Unity 3d, I know you can export your model with all animations in one file then later split these in Unity, but how do I go about exporting them individualy? so i have enemy@shoot/enemy@idle etc... and should I only be exporting the biped as the mesh is going to be animated by the biped? or do i need to export the mesh along with the animations?
