File Sharing, Mac and PC

[callmedonnie]

I've done some googling and there seem to be mutliple options out there. I was just looking for some views.

At the moment I live in a house w/ a few other people. We have a wireless network set up, no file sharing. I just acquired a Macbook and would like to share files between my PC without having to use my external hard drive everytime. What is the best way to go about doing this?
