This page describes the format and encryption of extdata, "extra data" stored on [[SD_Filesystem|SD card]] and NAND.

At /Nintendo 3DS/<SomeID>/<SomeID>/extdata/00000000 is directories for each title. Some titles have Quota.dat stored in these directories, not all titles use it. Then there's a sub-directory 00000000, which contains the actual extdata. Size and number of files in this dir varies per title.

==== Directories ====

When extdata is created, these directories are *always* created regardless of whether the title actually uses them.

* /icon Presumably contains the icon displayed in data management.

* /user Presumably contains the title's actual files for "extra data".

* /boss Presumably contains content downloaded/transferred via [[SpotPass]] and ~~possibly~~ [[StreetPass]]~~.(When~~ extdata ~~is created, this /boss directory is *always* created regardless of whether the title actually uses SpotPass/StreetPass~~.)

* /boss Presumably contains content downloaded/transferred via [[SpotPass]] in SD extdata, and in some cases [[StreetPass]] data in NAND extdata possibly.
