You can remove members, including shared members, from the Shared Library hierarchy and reuse them later. Orphan members are created when you remove members from the hierarchy. When you remove members, the member and all of its descendants are removed from the hierarchy and are moved to the orphan area as individual members without a hierarchy structure. When you remove a shared member, only that member is moved to the orphan area. The same member in other hierarchy structures is not removed.
You can view orphan members and also permanently delete orphan members.
