So I was working on my 1st project and it crashed on me. I reopened it and a message popped up "you have an unsaved project." I clicked that and restored my project. Then I closed it because I wanted to start on a 2nd project. I closed the 2nd project without saving because I don't want it. I reopened my 1st project and it popped up that message again because I didn't save my 2nd project. I accidentally restored it in place of my 1st project. Is there any way I could back up my 1st project?
