DLC titles have a different directory structure to most installed titles. This is because all DLC content for a given title is installed under the same Title ID, but DLC add-ons are usually separate purchases, hence the structure altered so any combination of DLC content can be installed. DLC titles can receive 'updates', this is usually in the form of more DLC content and/or DLC bug fixes. Individual DLC content can only be managed from with-in the application using the DLC.

'''"00000000"''' - This extra directory only found in DLC titles, contains the DLC [[NCCH]] content.
'''"<IndexSeparator>"''' - DLC [[NCCH]] contents are split across different directories, depending on the Content Index. Starting with 00000000, there is a directory for every 256 contents. All the directories are created upon install, which means some may be empty if the contents within its index range are not installed.
