The Simulation PSY Configurator installation has a set of pre-configured
data files that are specified in Preinstalled
simulation files. You can also create data files (NME or SPS) that
can be added by copying the files to the c:\system\data directory.
The files must have an extension of either NME or SPS; otherwise Simulation
PSY Configurator does not find them. The data file format is described in
the Introduction of
the Simulation PSY User Guide.
