+ * The <i>Compound File Table of Contents</i> chunk functions mainly as an index, allowing direct access to elements
+ * within a compound file. The CTOC chunk also contains information about the attributes of the entire file and of each
+ * media element within the file.
+ *
+ * To provide the maximum flexibility for defining compound file formats, the CTOC chunk can be customized at several
+ * levels. The CTOC chunk contains fields whose length and usage is defined by other CTOC fields. This parameterization
+ * adds complexity, but it provides flexibility to file format designers and allows applications to correctly read data
+ * without necessarily knowing the specific file format definition.
