What is a CIA file?

A CIA file is a CTR Importable Archive used to install game content to a Nintendo 3DS handheld device. It contains game content, TMD (title metadata), and a ticket (format that stores an encrypted titlekey). CIA files are commonly used for installing gamecard updates and mainly store 3DS eShop content.

More Information

The CIA format structure is similar to the .WAD format used by the Wii console. The sections that make up a CIA file are the certificate chain, ticket, TMD file data, content file data, and meta file data.

NOTE: The ctrtool can be used to read and extract CIA files.
