This may come as a surprise, however a Word document is not a text file; it is a complex file that, to all intents and purposes, contains text, but also graphics and images, formatting, page layout information, table of contents, headers and footers, foot notes, possibly revision information, and lots more. You can't concatenate two of those, only a very Word-savvy user can, and he would have to make some tough choices while doing so. :)
