How do I link to files in my Dropbox?
To link to a file in your Dropbox, first move it to the Public folder of your Dropbox. Hover your mouse over the file so that it’s highlighted, then click on the triangle that appears to the right of the file. Choose Copy public link from the dropdown menu. The URL that pops up is a link that anyone can use to access the file. It is a way to share files with people who don’t have Dropbox accounts. For details, see https://www.dropbox.com/help/16.
