How can anyone create downloadable products in Prestashop ???????

[kirk86]

Hey guys,
I was wondering if anyone has any idea or has already achieved to create an eshop where the customers pay for products
such as ebooks in pdf format and through the payment process after the confirmation they are redirected to a page from where they can download the products that they have purchased.

Take a look at http://prestashoptemplates.org/

I need something like in the following picture.

When you create / edit a product, there's a checkbox you can tick for Downloadable products, which lets you select the file that will be downloaded when a customer buys the product.
