How can I add a file to a product, so my customers can download it?
1. You sell a file and it should be accessible only for the customer who purchased it. (e-books, photos, music and other e-goods)
2. A file should be accessible for all customers. (For example instructions for product)
- upload your file to any hosting. if you don't have one, you can use Dropbox: it's free
- add a link to this file to your product's description using HTML editor.
