Well... A word file might be a bit much to ask for. You typically cant read in a Word file because .doc files are all pretty much binary or non-text. You could convert a doc file into a text file and then make a pdf file from that. Although I have heard (and I have never tried this and the manual never specifies how to use these functions) that you can (if running windows as your sever) that you can use COM to get information out of the files. Although as I said, I have not seen many examples of this... I did find one though...

But as I said it would be easier on you to just upload it as a txt file or something. Good Luck
