Mac Forums

Hello! I have a Mac running OSX 10.4 connected wirelessly with my airport extreme (first version) and a Sony VAIO laptop running Windows Vista Home Premium also connected wirelessly, but I'm having trouble sharing files from computer to computer and was wondering how I can setup a shared folder over the network (without too much hassle)? I also have an external hard drive connected directly to my Mac and would also like to share this drive with my laptop. Any suggestions?? Thanks!
