.CTC File Extension

Text file created by Microsoft Visual Studio, a Windows SDK; contains configuration data for a VSPackage command set; compiled into a managed VSPackage, native, or managed satellite DLL file.

CTC files have five sections with a beginning and ending identifier:

1. Command Placement - CMDPLACEMENT_SECTION & CMDPLACEMENT_END
2. Command Reuse - CMDUSED_SECTION & CMDUSED_END
3. Visibility - VISIBILITY_SECTION & VISIBILITY_END
4. Key Bindings - KEYBINDINGS_SECTION & KEYBINDINGS_END
5. Commands - CMDS_SECTION & CMDS_END

NOTE: Starting with Visual Studio 2008 and later, .VSCT files are used to define how menus and commands appear in VSPackages instead of CTC files.
