I worked on a drawing for the first half of today and left for lunch. When I came back, windows had auto updated and the drawing was gone. I hadn't saved the drawing at all since starting. Normally, I've been able to auto recover my drawings, but this time the drawing is no where to be found in the auto recover save folder. Is there anywhere else it could be or any tips anyone has to recover the drawing? I was 4 hours in and working on a dell percision m6800.
