.[[CIA]] - (CTR Importable Archive) It is the application compiled into an archive, ready to be installed to a designated location. A .CIA file can be extracted to install applications to the, CTR NAND, TWL NAND (part of the NAND used by DSi applications), and the SD card.  

.[[CIA]] - (CTR Importable Archive) This format allows the installation titles to the 3DS. CIA files can compile a CXI for installation to either the SDMC or CTR NAND. CIA files can also compile .SRL files (format for DS(i) executable images) for installation to the TWL NAND of the 3DS.
