Many storage providers have an option to share a file with a third party without access to your account with a publicly accessible link. Depending on the provider, the link may be auto expiring and no longer valid after a given period or a password can be set required to download the file. Some providers support to Request files… from others by creating an URL that allows others to add files to your account.

If you connect to a web root using ### FTP, SFTP or WebDAV, refer to HTTP URL on how to configure your bookmark to allow copying a HTTP URL for a selected file. With a valid configuration, you can open the corresponding HTTP URL of a file selected with your default web browser or copy the URL to the clipboard. To manage permissions, refer to UNIX Permissions (FTP/SFTP).
You must use [Cyberduck](https://cyberduck.io) to edit the Web URL in a bookmark. The Web URL will replace your server address in URLs available in *Copy URL* .
