retrieving lost file

Hi I have a Mac OS 10.13.6 High Sierra and I’m using Audacity 2.3.2
I had a recording that was about 85 minutes long. I saved it as an aup. Then i added a 60 second clip and hit save rather than save as, and lost the whole file. i can see the file name in audacity, but when i click it it loads an error message. i still have the data file with all the millions of little sound clips.
is there any way to recover this file?
Thanks for your time

Did you move or rename either the AUP file or the _data folder?
