This extension adds improved support for free products in Easy Digital Downloads. Instead of sending users through the standard checkout process when downloading a free file, Free Downloads will display a modal window to the user asking them to enter their email address. After entering their information, the user will be either redirected to the success page or a custom page of your choosing, or their file will be automatically downloaded, depending on your configuration.
The download modal also includes support for the users first and last name, user registration, custom text, as well as requiring email address verification before delivering files.
