DIR_MC_DUP_WRITE
<directory path>
Specifies the path to a directory in which duplicate model information is written. The directory specified by the DIR_MC_DUP_WRITE configuration option should be a central directory for all users.
Creo ModelCHECK writes a file called mc_dup_model.bin to this location when you exit Creo Parametric.
 
* This option is used only if the DIR_MC_DUP_WRITE_NT or DIR_MC_DUP_WRITE_U configuration options are not set. If none of the options are set, the directory from which Creo Parametric was started is used by default.
