A downloadable product is used to grant access to a file or page on your site. For example, a site that sells e-books will need to grant access to PDFs for customers who purchased the product. There are two ways to accomplish this.
The easiest way is to attach a file on your site to the variant. This is a quick and easy way to provide downloadable file. However, anyone who gets hold of the URL, will be able to download your file.
Your site is capable of securing file access by folder. This means you can upload your file to special secure folders and only grant the user access by a special role. Even if the URL is discovered, the user cannot download the file without permission.
