I have 3 new Windows 7 Pro desktop computers hooked to a 4 port linksys switch. Not connected to any internet. I have a folder labled "Files" on 1 of the computers desktop. I want to share this folder with the other 2 computers. Would I use Windows 7 HOMEGROUP or is there another way to do this? What steps do I take to right click and share out the "Files" folder on the desktop?
