Search drive for excel dependencies [closed]

I am currently simplifying a file structure of a company. It is a total mess. Currently I am doing the finance department, which has allot of dependencies between excel files. These files I cannot migrate to the new structure, because the location changes and the dependencies is lost.

Therefore I am in search of a tool to scan a folder and its sub-folders for excel dependencies. I want to list these and say: hey guys, what about these files?

Any ideas?

The code below

opens each file that sits in or below the directory specified by strStartFolder (ie "C:\temp") in this example using a recursive Dir
looks for any file links in each file
uses an array to hold then populate the final results

Pls change your path in strStartFolder to suit
