The following is a list of known file formats used by the 3DS.

Applications ( any executable code )

.CCI - Cart image. Burned into a ROM (or loaded by official debugging hardware). These are also the actual format of ROM dumps, and the response of read requests between a 3DS and a cartridge. See CCI.

.CXI - Executable image. Similar to above. The difference is CXI applications are installed onto [thus ran from] NAND. See http://3dbrew.org/wiki/CXI.

.CIA - Importable/installable application. An application ran from NAND after being loaded from an external [not NAND] source. The CIA format allows the CXI image to be imported/installed properly.

.CSU - System Update. Format varies slightly with revisions.

.CFA - Externalized ROM-FS. CXI data and ROMFS data can be separated into a list of external files instead of compiled into just 1 CXI image. (Normally not used.)

.NSA - Archive used by several of the communication protocols in the 3DS.

.RSF - Descriptive data used when outputting a CCI/CXI file. Specifies options such as: title, save type, and so on.

.AXF - Pre-assembled ARM code. before being linked into a CCI/CXI format.

Filesystem

The 3DS filesystem requires absolute paths. It can handle either short (8.3) and long (255 char maximum) file names.

MPO (Multi-Picture Object Format)
