File menu > New > Open file that has out-of-date map paths.
This file appears when you attempt to open a scene with bitmaps whose path is no longer current. This can happen if the bitmaps have been moved or deleted, or if the scene has been placed on a system with a different drive mapping than the system on which it was created.
