About CD files
The .CD extension primarily identifies a Visual Studio Class Diagram, a specialized developer file used to visualize the structure of classes and relationships in software projects. These files are XML-based but rely heavily on Microsoft Visual Studio to render the graphical layout. A major issue for developers is that the Class Designer component is no longer installed by default in newer versions of Visual Studio and is often restricted to paid editions (Professional/Enterprise), making these files inaccessible to users on the Community edition or those using text editors like VS Code. Opening them as raw text reveals unreadable XML metadata rather than the intended flowchart.
Alternatively, .CD files are frequently encountered as proprietary game data archives for LEGO video games developed by TT Games (e.g., LEGO Star Wars, LEGO Dimensions). In this context, the file is a binary container holding character definitions or physics data, strictly locked down to preventing easy modification or external viewing.
Conversion Advice:
For Diagrams: To share architecture designs with non-developers or archive documentation, convert the .cd diagram to PDF, PNG, or JPG. This preserves the visual layout without requiring the viewer to install a massive IDE.
For Game Files: These are not meant for standard conversion. Modders typically use hex editors or specific script extractors, but converting them to standard formats is generally not possible without breaking game functionality.
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 "Software 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 "Software 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.
