FM 7v3, Win 2K sp4

I have a solution (75 files, 45 users) converted from v6 that I
initially cleaned up file references on.

Problem is there are duplicate file references in the list, and I have
no way of knowing which field or script uses which reference.

Is there a procedure for working backwards from file reference to the
calling script or field(s) so I can clean up the reference list without
opening and inspecting thousands of scripts and fields?
