Recover overwritten files excel 2007

[ms02kk1]

Is it possible to recover overwritten files in excel 2007? By mistake when I created a new excel file I named it with the same name with an existing file that I had and when excel asked me if I want to replace the new file with the old one I said yes.

If you are on a network that uses daily back-ups, you could probably recover a backup. But if this is at home/no network, and you have overwritten an existing file, I think you are out of luck
