There are 3 computers in my room. 2 laptop and 1 PC. The PC and 1 laptop use Windows, and another laptop is Mac Leopard 10.5.4. I saw my friend, he has 2 PC (which I will call PC A and PC B), and when he want PC A to receive files from PC B, he just copy those files to a folder. And turn on PC B, go to that folder and it had been there. So simply. Do u know how to do that? But between Mac and Windows? Plzz help me. Thanks.
