While I agree,
I also will add that if you create the file first, then open it to edit, the autosave is more likely to work, and your users are more likely to be able to find the document.
(Note: I advocate fixing bad autosave implementations, but since that is often out of our control, it is still worth noting as an alternative. One of the Microsoft apps deleted it's own autosave files before writing the updated version to disk, so if the second write failed, your work was toast. I still have a nervous tic where my left hand twitches in the shape of ctl-s every 90 seconds or so...)
