Once a storage location has been used in any project, it can no longer be deleted, but can be hidden on the Storage screen by clicking the Delete icon (red circle with a trash can) next to the storage location. Click Delete to confirm the deletion. After deletion, the storage location cannot be recovered, however, restores to and from the storage location can be configured using HTML links or by searching for the Project that migrated / stored data to or from the storage location. See
Restore for more information.
