I installed XP. I'm running snow leopard. Everything seems to work ok but there is a 0 byte system file with an icon which is typical of a file that isn't associated correctly with any application. If I try to remove it or modify it or open it I always get messages saying i can't do it since its a system file. It seems clear it shouldn't be here but doesn't seem to be causing a problem, but in accounting a penny off can indicate big hidden problems, so it seems that I shouldn't ignore this. Does anyone have any ideas about why this file is where it is and what it means?
