The idl file extension is associated with Visual C++.

The idl file contains one or more interface definitions. Each interface definition is composed of an interface header and an interface body. The interface header is demarcated by square brackets. The interface body is contained in curly brackets.

All COM interfaces are defined using the Interface Definition Language (IDL). IDL is similar to C and C++ header files, with new syntax elements specific to distributed computing added. IDL files are compiled to create source files and binary type libraries that can be used by practically all programming environments.
