ADD_DUP_INFO_AUTO
<Y/N/A/D>
Configures how duplicate model information is written to the directory specified by the DIR_MC_DUP_WRITE configuration option.
Y—Always adds the model to the database.
N—Never adds the model information to the database.
A—Always asks the user before adding to or overwriting the existing information.
D—Adds the model information but does not overwrite the existing information.
When information is added to the directory, Creo ModelCHECK searches the directory for models with the same name. If a model with the same name is found, you can overwrite the existing data or cancel the addition.
