How do you put the file name in the footer without typing it?

To insert the file name in the footer without typing it, you can use the built-in feature in most Word processing software. In Microsoft Word, for example, go to the "Insert" tab, click on "Quick Parts," then select "Field." From there, choose "FileName" from the list of field names and ensure the "Add path to filename" option is unchecked if you only want the name. This will automatically display the current document's file name in the footer.
