hi guys, This morning i was trying to copy over some files from my windows laptop (XP PRO) to my iMac by just going into finder, finding the files and then dragging them onto my mac desktop. These files are pretty big about 600mb and some small music file 3-4mb. When i drag them over onto the desktop the file is created ok but the file is empty? This happens for anything that i transfer and it was working last night before i went out. I also tried going into itunes and adding a song to my library, then went and clicked on the song on the windows laptop but again nothing happens, not even a progress bar? I have also tried all of the above on my MacBook Pro and the same thing is happening? I find this very strange and would really appreciate it if you guys could help me out.
