Sharing a Local folder

[marktravis]

I got two computers running, one with Vista and one with 2K. I'd like to create a folder that I can share and access between the two computers, so I don't have to waste cd's by burning, or use my memory sticks constantly to transfer something from one computer to the other.

Now, I do find my own computer in 2K, under network places. In Vista, the same. But, how can I locate Vista in 2K and the other way 'round.

I guess this should be easy in Windows, but I am fairly new to the OS when it comes to these kind of operations. Not used to use tools like this in this OS, only Unix-like OS'.

Thanks for any help!
