You may find it frustrating that the SimpleLink host driver does not expose some file system functionality that are typically considered "built-in". These features include file listing, occupied/free space and file appending. The reason these features are not part of the file system stems from the fact that the file system was originally designed to serve only the internal cores of the device. Since it is impossible to add such features as patches, current production devices lack these services from the device. However, this section offers guidance on how to implement such features in the host application.
