I have noticed if you bring up the file properties there is a tab titled previous versions.

This may get you to a previously backed up copy somewhere. Following is from the link on the Previous Versions tab from one of my saved notepad files. I have not tested it though.


What are previous versions?
Previous versions are either copies of files and folders created by Windows Backup or copies of files and folders that Windows automatically saves as part of a restore point. You can use previous versions to restore files and folders that you accidentally modified or deleted, or that were damaged. Depending on the type of file or folder, you can open, save to a different location, or restore a previous version.
