how do you merge multiple files into one Word document in Office 2013?
I see the option in insert/text/object/create from file
but it only lets me add one file at a time.
I have 30 chapters of a book, each saved in a separate file, that I want to put together into one file.


how to do it?

May just be faster to just open a blank file, and then copy and paste each document one after another.

Control-A will highlight the entire document for you. Then control-C and V back and forth. Probably take 15 minutes to do it.
