There is additional information included in the readme file in the zip
Basically this utility reads your dayz profile to see which server you were on, and it updates as you change servers so always shows the current or most recent server.
It finds your file and shows this:
1) The filename it is using 2) The time the file was last modified 3) The IP and port # of the server 4) The Name of the Server You can choose a different file, (I don't recommend it), set the Server information, copy IP, copy server name, and exit.
