   Itunes, Private Data, Networking
  While at my friends house with my laptop, I noticed that my buddy was able to play a wide variety of music off of my computer and play them in Itunes (on his computer). So first thing I thought.. ohh, "I guess I've been really careless with my computer and put my folder to shared." .. However, upon typing my IP into the address bar like so "\\xxx.xxx.x.xxx" its shared folders were brought up.. and nothing but a few folders containing < 1MB were brought up.HOW is Itunes able to get the music off my computer if I didn't share my music folder? Or more important.. did I do something to windows that could have caused this?Note: We are both using Windows XP.   
  iTunes has the facility to share your library on a network, you might have accidentally switched it on?  That would mean your friend can connect to your library and stream your music from within iTunes providing you're on the same subnet, but actually copying it is impossible without dodgy third party tools.Go to Edit -> Preferences -> Sharing tab and see if your library is being shared.Either that or I'm not completely understanding what you're saying.   ;  I figured it out. Limewire was sharing my folder.. it wasn't apparent at first because even tho I had shut down Limewire, it still had a background process running. And this background process shares folders.. Thanks for your help, it gave me ideas :) !
