I have my auto save set for 1 minute.  Any time my program crashes, when I reopen it, I get prompted to recover the file I was working on at the time of the crash, I can choose yes or no. If i choose yes, I get back just about everything that I had completed prior to the crash.   If I choose no, Im assuming I start over from scratch or back to whatever I had the last time I may have worked on that file (Ive never chosen no in this situation, so Im really not sure)

When I exit a client file, I am prompted to Save and I can check yes or no.  If I check NO, the autosave that's been working in the background to protect me does NOT save anything.  The file will go back to how it was before I started working on it that session.
