I'm trying to search for a unique reference number in one
workbook in an archive directory. eg. one cell
containing - "03/405/ful", which could be located in one
of several hundred workbooks of archived files.

i can search the individual workbooks fine, but what
would the best way be to open up each file in the
directory (each with no predictable/regular name) and
search through them individually?

I guess, to summarise, "how would i open every file in a
folder one by one, when I don't know what name they will
have."
