If you have a file stored on Dropbox that you would like to share with the rest of the world, there are two fast ways to find and copy the file’s URL. This can only be done with files in the Public folder. Files stored in private or shared folders will not have the option to view the URL. Additionally, Dropbox only allows you to copy the URL for individual files, not the entire Public folder. This task can be accomplished both on the Dropbox website and within your local Dropbox client.
