CFSD File – What is .cfsd file and how to open it?

Definition

A CFSD file is a container format used by the Nintendo 3DS portable video game console to store Mii character data. It is an acronym for “Character Face Save Data” and contains information about the Mii’s physical appearance, clothing, and accessories. CFSD files are saved on the system’s internal memory or on an external SD card.

Usage

CFSD files are created when a Mii character is first created on the 3DS console. The file contains data such as the Mii’s facial features, hairstyle, eye color, and skin tone. It also stores information about the Mii’s clothing, accessories, and poses. CFSD files are used to display the Mii character in various applications on the 3DS, such as the Mii Plaza and games that support Mii characters. Users can also share CFSD files with other 3DS consoles via local or online multiplayer.

Opening CFSD Files on Windows

To open a CFSD file on a Windows computer, you will need to use a program that supports the file format. One option is the 3DS Mii Editor, a free and open-source software specifically designed for editing and managing Mii characters on the Nintendo 3DS console.

Once you have installed the 3DS Mii Editor, you can open a CFSD file by selecting “File” > “Open” from the top menu bar. Navigate to the location of the CFSD file on your computer, select it, and click “Open.” The file will be loaded into the editor, allowing you to view and modify the Mii character’s appearance, clothing, and other attributes.

Opening CFSD Files on macOS

To open a CFSD file on a macOS computer, you can use the Homebrew application. Homebrew is a package manager for macOS that allows you to install and manage software packages from the command line.

To install Homebrew, open a Terminal window and run the following command:

/usr/bin/ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”

Once Homebrew is installed, you can install the cfstools package, which includes a program called “cfsextract” that can be used to extract the contents of a CFSD file:

brew install cfstools

To extract the contents of a CFSD file, open a Terminal window and navigate to the directory where the file is located. Then, run the following command:

cfsextract filename.cfsd

This will create a new directory with the same name as the CFSD file, containing the extracted contents.

CFSD File Structure

A CFSD file (3DS Mii) is a Nintendo-developed binary file format used to store Mii character data on the Nintendo 3DS handheld video game console. The format is employed by several Nintendo software applications, including the Mii Maker and Miiverse, allowing users to create, customize, and share personalized Mii avatars. CFSD files contain a variety of data related to a Mii, including its physical appearance, clothing, accessories, and personal information. The file structure is organized into four main sections: header, body, face, and accessories.

Header Section

The header section of a CFSD file contains general metadata about the Mii, such as its name, age, gender, and any special flags. It also stores information about the file format version and the size of the body, face, and accessories sections. The header is followed by the body section, which contains the Mii’s physical characteristics, such as its body shape, skin color, and hair style. This section also includes information about the Mii’s clothing, including tops, bottoms, shoes, and other accessories. The face section contains data about the Mii’s facial features, including its eyes, nose, mouth, and eyebrows. Finally, the accessories section stores information about any additional accessories the Mii may be wearing, such as hats, glasses, and jewelry.
