CDF stands for Content Definition File. The CDF file format is used by groups and organizations to share abstract enterprise content management data. The files created in this format are saved with the .cdf file suffix in an XML-based data format.
The .cdf file extension is also commonly used for comma delimited data files, Cyberspace Description Format files, InstallShield files, MicroSim PCBoard files and Unidata Network files.
