Question : Exchange 2010 DAG witness directory

hi

i have created a dag of 3 mailbox server nodes, the witness directory and server are on a exchange 2010 hub transport server. Per database i have enabled 1 active and 1 passive copy.
now when i logged in to the witness server and checked the witness directory there are no files or folders available inside. is it normal or something is wrong? how do i test or check if my dag configuration is correct?

thanks

File share witness is only needed when you have an even number of members in the DAG, odd numbered nodes do not use a witness server.
