CKD File – What is .ckd file and how to open it?

CKD File Format

A CKD file is a game data file that uses the UbiArt Framework, developed by Ubisoft. The UbiArt Framework is a video game engine used to develop 2D and 3D games. CKD files store game assets such as textures, models, animations, and sound effects. They are typically found in games developed by Ubisoft, such as Rayman Origins, Rayman Legends, and Valiant Hearts.

CKD files are compiled from source files using the UbiArt Framework Compiler. The compiler generates a binary file that can be read by the game engine. CKD files are compressed to reduce their file size. They can be decompressed using the UbiArt Framework Decompiler.

CKD files are essential for the functioning of games developed using the UbiArt Framework. They contain all the data that is needed to render the game’s graphics, play the game’s sound effects, and control the game’s gameplay. Without CKD files, games developed using the UbiArt Framework would not be able to run.

Identifying CKD Files

CKD files, carrying the file extension .CKD, stand for “UbiArt Framework Cooked Asset.” This proprietary format is utilized by games developed using the UbiArt Framework, a game engine created by Ubisoft. CKD files contain compiled assets necessary for game execution, including character models, textures, animations, audio, and level data. They are typically packaged within game archives (.UPK files) to facilitate distribution and management.

Opening CKD Files

Directly opening and accessing CKD files requires specialized tools or software. Ubisoft has not released any official tools for working with CKD files, so third-party applications are often used. One popular tool is ckdtools, an open-source software package that allows users to extract, decompile, and modify CKD assets. Other tools, such as CrypticCKD or UPK Explorer, can also be used to handle CKD files within UPK archives. It’s important to note that modifying CKD files can have unintended consequences on game stability and behavior, so users should proceed with caution.

CKD File Association

The .CKD file extension is primarily associated with the UbiArt Framework, a game engine developed by Ubisoft. UbiArt Framework is utilized in the creation of various video games, including Rayman Origins, Rayman Legends, and Child of Light. Within the framework, .CKD files serve as cooked assets, meaning they are optimized versions of original asset files, such as textures, models, and animations. The cooking process involves compressing and optimizing these assets for efficient loading and rendering during gameplay.

CKD File Structure and Contents

.CKD files employ a proprietary format designed specifically for the UbiArt Framework. The internal structure of these files is not publicly documented, making them difficult to modify or extract without specialized tools. However, it is known that .CKD files contain various types of data, including textures, models, and animation data. The data is typically stored in a compressed format to minimize file size and optimize loading times. In some cases, .CKD files may also include additional metadata, such as file dependencies or version information.
