You'll need to recursively search the drive for files matching the extensions of interest, either using ADIR or the Scripting.FileSystemObject to wander through the tree, and once you have the possible files, use the appropriate automation server (Word.Application or Excel.Application in this case) to try to open each file in the list of matching files.

There was a thread a couple of weeks back, take at look at my message Re: Get a collection of sub folders from a parent folder Thread #288982 Message #289075; George Tasker posted code earlier in the threadshowing the ADIR() approach.
