.CCSCC File Extension

Source code control file used by ClearCase, a management application for software development projects; stores information about projects under source control; used for integrating Microsoft Visual Studio projects with ClearCase.

CCSCC files are used in multi-user projects. In particular, they help handle the situation when a second user chooses the "Open from Source Control" option for a Virtual Project. CCSCC files need to be under ClearCase source control in order to enable this capability.

NOTE: CCSCC files were only used for integration with Visual Studio .NET prior to VS.NET 2005.
