Leaving backups in this folder will break the code, as it iterates through each file, and create a class form them.

Thanks for the help,

I've copied the following files to the corresponding directories:

process_2checkout.php - (root or /cart/ folder, the rest of the folder below sit within the cart folder)
includes/modules/payment/as2checkout.php
includes/languages/english/modules/payment/as2checkout.php
includes/extra_configures/as2checkout_defines.php
