File Sharing Between XP and Vista?

So I just received my new computer and I basically want to be able to achieve files and stream media from the XP computer to Vista....what's the easiest way to do this? If anyone can dig up a tutorial for me that would be great.

There's a website on the Internet called Google. Most people call it a search engine. You can search a lot of information about anything.

This took 3 seconds of my time. I usually bill by the hour, but I'll let this one slide.
