To convert other file formats to the "Class Diagram Model" file type, you need software like Microsoft Visual Studio or a similar tool.
About CD files
The .cd file extension is primarily used for Visual Studio Class Diagram files. These files store the visual layout and structural metadata of object-oriented classes within a C# or VB.NET programming project. The file uses a standard UTF-8 XML structure to map out interfaces, classes, enums, and their relationships.
Secondary uses include highly proprietary game data formats. This includes character data files for LEGO video games developed by Traveller's Tales and game installation data archives used by the Electronic Arts Origin platform.
Users often need to convert Visual Studio .cd diagrams because viewing them requires Microsoft Visual Studio with the specific Class Designer workload installed. This makes it impossible to share the visual design with stakeholders who do not have developer tools. Furthermore, game-related .cd files are closed, proprietary binary chunks that lack official documentation, meaning they are locked to the specific game engine.
For class diagrams, the best target formats are image formats like PNG or SVG to preserve the visual representation, or standard XML to parse the raw code references. Standard online converters fail to process these properly because rendering the diagram requires understanding the linked source code in the local project environment.
The game data variations are notoriously difficult to open or convert. Only the original software or specialized community modding tools can properly read or export the data. Our tool can inspect the binary file and show underlying text or internal content. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your CD file, detects the exact format, and lets you read the text inside.
If you want to convert CD file to MP3, USB, MP4, ISO, JS, TS, PY, JAVA, CPP, C, CS or PHP, you can use Microsoft Visual Studio or similar software from the "Visual Studio Class Diagram" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to CD, try Microsoft Visual Studio or another comparable tool in the "Visual Studio Class Diagram" category.
The CD Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our CD converter.
