+\section faq_ext_mapping My file with a custom extension is not parsed (properly) (anymore).
+
+Doxygen only parses files that are specified as input (via the \ref cfg_input "INPUT" tag)
+and that match a specified extension (mentioned in \ref cfg_file_patterns "FILE_PATTERNS")
+The list of files is then reduced by excluding files listed as \ref cfg_exclude "EXCLUDE" or 
+files that match the patterns set by \ref cfg_exclude_patterns "EXCLUDE_PATTERNS".
+
+In the past doxygen parsed all files with an unknown extension as C files which could lead to
+undesired results. Since version 1.8.8, doxygen requires that you specify a mapping that tells
+for a certain file extension, which parser to use. 
+This mapping is specified using the \ref cfg_extension_mapping "EXTENSION_MAPPING" tag.
+If no mapping is specified the file's contents will be ignored.
