Typically, within a single DOC/DOCX file you can insert a simply cross
reference to another heading or figure for example (Alt + I + N + R).

My problem is that my company employs a standard where every section of a
document is contained within a separate DOC/DOCX file. I cannot figure out
how to insert these seemingly simple, yet elegant cross references in one
file that are pointing to a heading or figure in another file.

At least to simplify matters, all files employ the same heading formatting
levels etc.

How can I insert a cross reference in file 'A' to that points to a specific
heading or figure in file 'B'?

Thanks in advance.
