Lost file after moving to desktop

I’m using Audacity 2.4.2.

I “saved as” a four hour file to my desktop, and then somehow it disappeared. I cannot find it anywhere. It even removed itself from the “recent files” in audacity. I’ve search for 4 hours now and cannot find it anywhere.

I think exactly what I did was “save as” to desktop, then I went to the desktop and tried to open the file and got an error message, so I shutdown audacity, opened it back up and could never open the file again. And then it even disappeared from the “recent files” in audacity as I said. Incredibly frustrating.

Is there anyway to get the file back? I lost a huge amount of work. Anyone have any ideas??
