3. Click on the old file name.
4. Message pops up "File name does not exist." Close it.
5. Repeat steps 2 and 3.
Old file name is shown again, step #4 is repeated.
File name should be deleted from the list of recent documents.
User Profile Reset: No
Additionally, upon the first discovery that a file no longer exists, a right-click on the dead link might open a file manager window to support the user in locating a renamed or shifted file.
