## Preprocessing Files

In the Project Explorer or Symbian Project Navigator views you can preprocess source files (.c, .cpp, .cia), header files (.h), and resource files (.rss) by right-clicking the source file and then selecting the Preprocess command. Use the Preprocess preference panel to specify the preprocessor settings.

When preprocessing resource files that use more than one language, the Select Language dialog appears asking you to select the language to preprocess.
