How do I have FM7 cycle through a directory of Excel Workbiiks?

[MSS49]

I need to convert many directories each containing many Excel workbooks to FM7. The sequence of events would be:
1- Get the Excel workbook into FM7 workfile (Convert).
2- Edit records and populate another FM7 File (FM7 Script).
3- Get the next Excel Workbook and repeat the process until the directory end is reached.

How can I have FM7 automatically cycle through each directory?
