It opened again named 'Document1' with nothing lost. What I obviously wanted so I clicked 'Open'. It asked me if I wanted to reopen Word and restore my files I don't know if it was saving to OneDrive or my computer (I only use Office for schoolwork, so I'm not an expert at this). When I realized I hadn't saved I tried to but whilst saving, Word crashed. I forgot to manually save, but in the back of my head I guess I knew it would autosave. So I have been working on a Word file for 3 days, and I continuously had Word open for 3 days.
