Tracking linked file usage

[SwordAngel]

I have an Excel 2003 spreadsheet that I am editing with Excel 2007. I am not
the original author of the spreadsheet. I notice that the spreadsheet is
supposed to have two linked files. I have installed the Ultimate Add-In (from
www.dom-and-lis.co.uk) and used it to generate a Links Report.

The report has three sections:
- Linked Files
- Linked Names
- Linked Formulae

According to the report, it appears that one of the linked files, "Book1",
is used in a couple of linked formulae. The other linked file "Book2",
however, does not seem to be actually used anywhere, aside from being linked.

How can I be sure if "Book2" is, in fact, not used at all?

Copy the workbook and Remove the links from book2 using the menu: Edit -
Links and seeing if there is any errors.

I've seen cases where the workbook is corrupted and excel still thinks there
are links when there aren't any. I've gone and delete sheets one at a time
until I found which sheet had the link. Then delete rows and columns to find
the link and never found the link. I finally copied the worksheet that had
the link to a new workbook and the link went away (it was never really there).
