I was curious how to do this on Windows Vista/Windows 7. Here's what I'm trying to accomplish. I want to stream some of my video files from a PC to my iPad. I can do this using a third party app that runs on my iPad that can connect to a computer via a WiFi network. I managed to do this quite easily on Windows XP and I can stream AVI files from the "C:\Documents and Settings\All Users\Documents" folder. All I did is this -- I right-clicked on the Documents folder there and selected Properties, then Sharing tab and set "Share this folder on the network", named it and OK'ed it. After that I can easily see that folder from the app running on my iPad and stream files out of it. Windows Vista and Windows 7 aren't as easy to set up and they don't have the same controls as Windows XP. So can someone help me set it up there?
