Provide downloads link in customer receipt?

Is there a way to provide the direct links to the downloadable files in the receipt a customer receives after purchasing a downloadable product?  In other words, it lists the file names in the invoice, can't those also be made into direct links to download from?  

Never mind. I discovered what the problem was. The emailed receipts were in my spam folder so gmail was not displaying them as a link. When I took them out of spam the links showed up and worked. Sorry about that.
