One other possibility,

Do you have IT people who do daily backups?
Yesterdays back-up will be unchanged.

The short answer is you don't.

If you did a Save As to a different directory or changed the
name slightly, then the original file will still be intact and living
in it's original directory, but if you just did a straight Save
over the top of your existing file, then, unfortunately it
is gone for good.
