DIR_MC_DUP_READ
<directory path>
Specifies the path to a directory from which duplicate model information is read. Creo ModelCHECK reads a file called mc_dup_model.bin from this location. The directory specified by the DIR_MC_DUP_READ configuration option should be a common directory for all users.
Reuse this option up to 50 times to specify more than one location to read from. Use a new line for every location.
 
* This option is used only if the DIR_MC_DUP_READ_NT or DIR_MC_DUP_READ_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.
