The files are later displayed on the frontend product page as a downloadable links, displayed by buttons and you can specify the button name and order. The file extensions that are allowed for upload are the same, that are configured in the store's settings.

This extension can be usefull to provide the customer with the full information about your product like warranty documents, instructions,
ingredients and so on.

The extension is very easy to install and does not contain core file modifications.
