Adding additional features to any folder turns it into a Dropbox Space. These features make it easy to organize your content and stay on top of things.
Features of a Space include:
You can give people can-edit or view-only access to a Space the same way you would a folder. Only people with can-edit access to a Space can edit its features. When you turn a folder into a Space, it’s shared with the same people it was shared with before, with the same can-edit and view-only permissions.
Spaces can be viewed on dropbox.com, the Dropbox desktop app, and the Dropbox mobile app in the same places you can view folders.
