Fortunately, my lab partner had older versions of most of our files and I had some more recent ones saved, but we still lost 7+ hours of work to that mistake, just over 24 hours before the thing was due . I of course felt terrible, but my lab partner was fortunately nice about it, and I ended up coding up until 3:30 this morning and then got up early to continue... I'm still a little behind where we wanted to be, but fortunately not as much.

So, lesson learned: always back up your files!

Ugh.

I usually end up with 6 or 7 versions of my CNC programs, each with a different name, to avoid the problem. Gets confusing at times but nowhere near as frustrating as over-writing a known good file.
