The .c3xml file stores a chemical model created in Chem3D in XML format.
Chem3D is designed for chemists and biologists who need to build and examine three-dimensional molecular models. The c3xml file belongs to Chem3D's own project and model data rather than being a general-purpose XML format.
Install Chem3D on Microsoft Windows, then use its Open command to load the .c3xml file. If the file does not open, it may require a compatible Chem3D version.
Open the file in Chem3D and use the program's Save As or export command to choose an available target format. The exact export options depend on the installed Chem3D version.
