What is a CHARINFO file?
A CHARINFO file is a virtual avatar file format used by the Nintendo Switch game console to store Mii characters. It contains data that represents the Mii's appearance, including facial features, body attributes, and clothing. CHARINFO files enable games like Miitopia and Super Smash Bros. Ultimate to create and use customizable avatars.
More Information
CHARINFO files are typically associated with specific game directories on the Nintendo Switch and are crucial for loading and displaying Mii avatars within those games. Players often interact with these files indirectly, as they are automatically generated and updated by the system or games rather than manually created by users. Developers have, however, created tools to view and edit these files, although this is not officially endorsed by Nintendo.
The file extension for Mii characters in CHARINFO format is often .charinfo, though some versions, like those used in Mario Golf: Super Rush, may employ the .mii extension. Both extensions serve similar purposes but may vary in format details or application usage.
NOTE: The website MiiLibrary provides copies of some official CHARINFO files.
How to open a CHARINFO file
CHARINFO files are not meant to opened or edited. Those who have modified their Nintendo Switch to use homebrew firmware can use MiiPort to import or export CHARINFO files from their Switch.
You can also open CHARINFO files with Mii Creator. The program is available via the Discord platform online.
