My mac is currently running OS X 10.6.6 I had a file on my desktop, then i accidentally moved another file with the same name to the desktop as well and it deleted the first file and replaced it with the second file. I tried pressing apple+z (command+z) but all the does it take away the one i moved there but doesn't bring back the original file. I have also looked through my trash but its not in there either. IS IT GONE FOREVER??
