I found that the setting “File>Preferences>Communication>Telemetry> Have Direct Dial directory saved in the DB Directory” does make a difference in how the program behaves.

Telemetry > Have Direct Dial directory saved in the DB Directory” does make a difference in how the program behaves.

In your case I would keep this unchecked as you will want to keep you DCD regardless if you change DB folders.

You should be able to copy from one machine to another with just the DCD.GRD file and place it in the “C:\Program Files\Diamond\Centurion Gold” for each workstation.
