Recovered model will not open!

I was working on my model on a desktop computer and saved it on an external drive. Somehow the file disappeared from the drive but i got to get it back through desk drill. Now. when I open the skp file it says “this does not appear to be a sketchup model”. I’ve tried opening it on sketchup web and through the application but nothing works.

Something in the save process is being interrupted. This is a known issue. One must first save to a local drive then transfer it to the external drive. When opening the file it must first be transferred to the local drive then opened.
