When you re-open a file after it has closed abnormally, the Document Recovery task pane appears, and lists stored extra versions of the files that you have been working on. You can select the version of the file that you want to restore immediately, and continue working. You can also keep other recovered versions and view them later by selecting one of the following in the Document Recovery task pane:
Yes, I want to view these files later (safest option) Select this option if you are not sure whether you need the data in the recovered versions of the files.
No, remove the files. I have saved the files I need Select this option if you are sure you don't need the data in the recovered versions of the files.
