Exporting Animations?

Hello all!

I’m new to the community (and blender) and wanted to know if it was possible to export my animations in blender into XSI and eventually HL2 for a mod i’m trying to create. I’ve tried some things on my own and the end result is usually a couple hundred files, each one being a different frame it seems. I want to know if this is normal, and if it is how I can use it!

Thanks in advance,
