Microsoft Channel Definition Format
CDF is a file extension for the Microsoft Channel Definition Format. The Channel Definition Format was an application of Extensible Markup Langugage (XML) that Microsoft proposed as a standard way to describe a Web site channel, consisting of a website or group of sites.
A CDF file identifies the page and subpages a user sees after selecting a channel on the browser.
Channels were removed from Internet Explorer in version 7.
The CDF file extension is also associated with Netcdf graphic files.
