If you have file extensions displayed (that is, if you are seeing
Filename.doc instead of just Filename) and try to rename the file without
the .doc extension, you will get this message. If you don't have file
extensions displayed, you won't have to worry about it. Although it is far
preferable (for a number of reasons) to retain the display of file
extensions, you can make the change in Windows Control Panel | Folder
Options | View: "Hide file extensions for known file types."
