I need the best working application which i can execute inside mac os x snow leopard 32 bit 10.6.8 to turn my imac into a files server so that i can transfer files to my windows 8 OS laptop. Basically i want to be able to download files from this imac to my windows 8 pc laptop by establishing a local area network file server on THE MAC ONLY.

I do not want to process to consume any of my bandwith that i get with my service provider.

Thanks very much.
