I need to develop a macro that methodically runs through 10 of the same word document(all saved in the same folder) and delete the filler text.

Context: I built a large document(100+ pages) and sent it out to some friends. They are filling in their own text and sending the file back to me. I only want to keep their responses.

Request: Develop a macro to delete all the words I sent out, and only see their responses. The document is very rigid and should be simple to select the section i sent out. no?
