	CIA stands for '''C'''TR '''I'''mportable '''A'''rchive. This format allows the installation titles to the 3DS. CIA files and titles on [[Title list\|Nintendo's CDN]] contain identical data. As a consequence, valid CIA files can be generated from CDN content. This also means CIA files can contain anything that titles on Nintendo's CDN can contain.

	Under normal circumstances CIA files are used where downloading a title is impractical or not possible. Such as distributing a [[Download Play]] child, or installing forced Gamecard updates. Those CIA(s) are stored by the titles in question, in an auxiliary [[NCCH#CFA\|CFA]] file.		Under normal circumstances CIA files are used where downloading a title is impractical or not possible.
