Hello. 1. Yes you need a router/switch, wired or wifi2. Both computers in the same workgroup. 3. Turn on sharing for any folder you want to share. Share with everyone4. Check security, make sure the group everyone is on the list. If it isn't add it and give it the permissions you desire.The methods on how to do these are a bit different between the 2 OS, but the overall idea remains the same. If any questions, google the question + OS (XP or Win7) and you should be golden. 03 Jan 2011 @ 19:1
