If you are like me, wanting to be sure that you always have the most recent copy of your file, without caring about saving every time, then you might have enabled 'Auto-save every X minutes' under Tools  > Options > Workspace > Save.  However, "Save to Checkpoint" might also be an option for you, when you don't want to fill up your hard drive storage with extra data.
