I was sorting a bunch of miscellaneous comments from word documents into one document. The one document had been titled and saved after one comment was put in it. Then I spent an hour cut and pasting paragraphs from other documents into that document. Then I was closing a bunch of other documents and when I got to this one, I clicked "don't save" instead of "save" by mistake. So the document saved without all of the added data. Is there any way to retrieve the document as it was before I clicked "don't save" after closing it?
