Allow customers to upload Zip

[AdlerWolf]

Hello,

 I am a business student and have, in the lecture e-business ,the task

to set up a Webshop. For the Websop I chose Prestashop, as it well meets the requirements.

But unfortunately I need a function that is not available as default.

The customers can upload a Zip File while ordering.

I have already found the product customization. This allows upload images. I tried to adjust the function to upload zip files can. That did not work.

 

Can there who help me? It does not have to be beautiful. There should only be functioning and Free.

 

You would help me a lot!
