I have a 53-page document -“File1”- that contains 35 bookmarks, with roughly 40 cross-reference fields related to them. When I saved the file under a new name -“File2”- (so that I could create a Table of Contents without risking damage to the original file), I somehow corrupted the bookmark list in “File2” so that it only contains one of the original bookmarks. Therefore, “File2” contains roughly 40 “Error! Bookmark not defined.” messages.
It will take several hours work to manually compare “File2” and “File1” and re-enter each bookmark anew (I know from previous experience how tedious it can be). Is there a way to copy the bookmarks from “File1” to “File2”?
