I had a huge .txt file that was a database dump and very valuable. I was trying to extract the data from it with a third-party program, but made a mistake. It basically wrote over the file with a 0-byte file of the same name. I have no backup (obviously or I wouldn't be posting here

). I can't imagine that all of the 1s and 0s were written over, so how can I get back the data? Thank you!
