CFC is the extension given to files related to the development platform for building web applications called ColdFusion. CFC files are used to store application components developed on the platform. These files are based on CFML (ColdFusion Markup Language). CFC files most often contain code that allows you to manipulate information stored in databases, but they can also perform other tasks.

ColdFusion is a solution developed by Adobe that allows you to effectively create complex applications, including those that work in the client-server architecture.
