Yesterday I completed the "Whodunit" exercise. Today I came back to start the "Resize" exercise, and I've discovered that (at least) two files are missing from the Whodunit directory - specifically, my file whodunit.c, and my file verdict.bmp - i.e. the required outputs for the exercise! As you can imagine, this is quite frustrating. It won't be that much work to re-create the whodunit.c code, but it's pretty worrying that the files have disappeared! I'm as sure as I can be that I saved them both - hitting cmd-S every 10 seconds is like a physical tick for me! NB, I'm working online at all times.
My question is - is there any way to go back through my history on the CS50IDE to find previous versions of file structures, and re-instate the files? Or even just to find out what happened?
Many thanks in advance for your help.
