# External URL links This feature allows creation of links to notes, folder, and tags. When opening such link Joplin will start, unless it's already running, and open the corresponding item. To create a link, right click a note, a folder, or a tag in the sidebar and select "Copy external link". The link will be copied to clipboard. ## Link format * `joplin://x-callback-url/openNote?id=` for note * `joplin://x-callback-url/openFolder?id=` for folder * `joplin://x-callback-url/openTag?id=` for tag ## Known problems On macOS if Joplin isn't running it will start but it won't open the note.
