ParamFile configuration parameter (TDK)
Syntax (prefix with dash in a Generation Settings Scheme):
ParamFile=<path and name of configuration parameter file>
A ParamFile configuration parameter references and uses a Configuration Parameter File from a Configuration Parameter File.
Configuration Parameter Files provide a way of setting Configuration Parameters consistently for multiple users.
By default, TDK (and ACS) looks in the ItsShadow\Exe folder a Configuration Parameter File named ShdConfig.par and then TDK looks in the same folder for a Configuration Parameter File named TdkConfig.par. When a Configuration Parameter File is found, that file's Configuration Parameters are processed.
Within a Configuration Parameter file, you can reference other Configuration Parameter Files through the ParamFile configuration parameter.
Note that you can use the ParamFile configuration parameter through the registry or a Generation Settings Scheme to make TDK use an alternative Configuration Parameter File, but this is not recommended.

ACS also looks for and uses the ShdConfig.par Configuration Parameter File.
ParamFile=C:\ConfigFiles\MyTdkConfig.par
ParamFile=H:\SharedConfigFiles\BaseTdkConfig.par
