The Project Tree is used when using the Change Management features of DI Studio. You can create a project repository for each developer. The developed can then check-out items from the main repository, make some changes and then check the item back in to the main repository. This way an audit trail is made of the changes made to an item. See the following link for more details on the change management features.
