All users except collaborators can add folders and projects to spaces for which they're an admin or have a Full or Editor access role.
You can use tagging to add existing folders or projects to other spaces. They'll appear in the left-hand navigation of any space they're tagged in. Folders and projects can be located in any number of spaces.
When you add a folder to a project or space, it'll be shared with users who have access to that space.
Navigate to the relevant folder or project and open its info panel. 1
Tags are listed under the folder or project's title. Click the + icon 2 to add a new one.
Scroll through the list of available locations for tagging until you find the relevant space, 3 or search for it.
A pop-up will appear alerting you if the folder or project has been shared with new users as a result of the tag.
You can also hover over existing tags and click x to remove the item from a particular space.
All the projects and folders added to a space appear in its left-hand navigation menu under Projects and folders. The projects that appear in this menu can be filtered according to their status.
