 If during lookup a top-level name is not found in the unnamed top-level scope, the search continues in the package hierarchies stored in these directories.
 
 \begin{example}
-\Cref{fig:roots} below shows an example \lstinline!MODELICAPATH! = \filename{"C:\textbackslash{}library;C:\textbackslash{}lib1;C:\textbackslash{}lib2"}, with three directories containing the roots of the package hierarchies \lstinline!Modelica!, \lstinline!MyLib!, and \lstinline!ComplexNumbers!.
+\Cref{fig:roots} below shows an example \lstinline!MODELICAPATH! = \filename{C:\textbackslash{}library;C:\textbackslash{}lib1;C:\textbackslash{}lib2}, with three directories containing the roots of the package hierarchies \lstinline!Modelica!, \lstinline!MyLib!, and \lstinline!ComplexNumbers!.
 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}.
