Thank you for your reply, kthchew. Running the delete command without sudo gives an 'Operation not permitted' error, that's why I ran it with sudo. (The exact error is: 'An error was encountered processing the command (domain=NSCocoaErrorDomain, code=513): “data” couldn’t be moved because you don’t have permission to access “Deleting-A78FAE81-FF58-45D0-AE80-FD8B9ABAF775”.')
