Comapre multiple documents

Hi Team,
I have one document which send to four users. Now all these users modify documents. I need to merge these documents and create final document which have all users change. Can you guide me how can I do this.

@Vipin_Paliwal Unfortunately, there is no such functionality. Could you please confirm the feature you are asking about is Combine feature in MS Word?

Hi, @Vipin_Paliwal

Did you move foward in this issue? I found this post and I think that, if you need only to concatenate files in a single one, it should work for you.

I hope it helps.
