Word preview headers

Hi
is there a way to preview headers of Microsoft word documents without having to open the file that would also show any tracked changes in the display. In file explorer with the preview pane on I can only see the body of the document, just thought there might be a quick way to view them without opening the file itself as it takes a while to open documents now as I can no longer open multiple files in the same word window using word office 365. If this isn't possible to preview headers or open multiple files in one window, does anyone know a way to pull headers from multiple word documents in a folder and paste them all into one file.
thanks for your time
