Lost File On Mac

[Emmer390]

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?? 🙁

It is gone, as it has been OVERWRITTEN, which means the original data has been replaced with new data.

If you have Time Machine running incremental backups, you could check to see if the file you need was backed up.
