I installed the add customer in admin mod on zen cart 1.5.1. When I clicked on the link "Formatting the CSV" in my admin area under customer>add....a page not found opens with the link at the top with the following link prefix ending, add_customers_formatting_csv.html I have look in the admin folder and can't find anywhere add_customers_formatting_csv.html file

My question:

Where would I find this file in my file manager?
How do I get the link to open to the add_customers_formatting_csv.html page?
