 The first two are represented as the subdirectories \filename{C:\textbackslash{}library\textbackslash{}Modelica} and \filename{C:\textbackslash{}lib1\textbackslash{}MyLib}, whereas the third is stored as the file \filename{C:\textbackslash{}lib2\textbackslash{}ComplexNumbers.mo}.

 This subdirectory must have a file \filename{package.mo} containing a definition of the package \lstinline!MyLib!, according to the Modelica rules on how to map a package hierarchy to the file system.
 The subpackage \lstinline!Pack2! is stored in its own subdirectory or file in the subdirectory \filename{MyLib}.
 In this case the search succeeds and the package \lstinline!MyLib.Pack2! is loaded into the environment.
