A downloadable product can be anything that you can deliver as a file, such as an eBook, music, video, software application, or an update. You can offer an album for sale, and sell each song individually. You can also use a downloadable product to deliver an electronic version of your product catalog.
Because the actual download doesn’t become available until after the purchase, you can provide samples, such as an excerpt from a book or a clip from an audio file, that the customer can try from the product page.
Downloadable products can be configured to require that the customer log in to an account to receive the link, or can be sent by email and shared with others. The status of the order before the download becomes available, default values, and other delivery options are set in the configuration.
The files for download can be either uploaded to your server, or linked to on a different server on the Internet.
