HELP - Oversaved project

Hey, I really need help on this one. I recorded an interview, saved it and clicked the exit ‘X’ on the track, leaving the program open. Happy days. I then recorded a second interview and when I was finished I hit save instead of save as and the previous project got oversaved. It’s gone. I’ve checked the data files, it’s all the new recording. Can anyone suggest a fix, please

If Audacity is still open, use “Undo” (Ctrl + Z) repeatedly until you get back to the first project, then save it with “Save Project As” (and give it a new name).

If Audacity has been closed, then unfortunately the first project is gone and lost forever, unless you have a backup.
