ftp to PC

I'm fairly new to networking and have just figured out how to share files between my jailbroken iPhone and my Macbook Pro through sftp. I was wondering if theres something similar I can do to get the same kind of thing going with my Vista PC. I have searched all over the internet and can not find a straightforward way to do this. Forgive me if this is a dumb question.

You can create a share on the PC and then connect to that share from the Mac.

FTP is not really needed but you could use it as well.

Thanks for the reply. I'm really trying to figure out why FTP isn't working. I've enabled sharing on both computers and all that but I can't get it to work.

FTP = File Transfer Protocol

In order to use it, you must have an FTP server running. This is not file sharing but rather an entirely different service.
