Hide Filepath provides a way to hide absolute paths to files on the page source, even if your Drupal instance is using the Public download method.
It especially comes in handy if you want users to be prompted to login first before viewing or downloading a file.
Note: This is not a security module. It's only "security through obscurity". If a direct file-path is known, it is still accessible.
Also, this module currently only supports file fields attached to the Node entity.
