Thanks Charles. The reason why i am using this method is because i have 7 authors, each working on a different parts of a report. They are doing edits concurrently. We cannot have all 7 working on 1 physical document and eventhough we can copy paste into 1, it is prone to error. I have read in many sites that MS word master document template is not an ideal solution. But is there other better ways to manage it ? If fact, i find adobe acrobat PDF merge is very useful as it retains the formating and layout, but it is difficult for reviewers to work on. Please let me know if there is other tools i can buy to add into MS word for me to better manage concurrent edits of multiple documents. Thank you.
