Microsoft Visual C++ Workbench Information File (VCW) is a project configuration format developed by Microsoft for use with its legacy development environments. This format primarily stores workspace settings, debugger configurations, and project metadata for managing source code builds within early versions of the Visual Studio ecosystem. As an obsolete text-based file, it is considered safe for general use and lacks executable capabilities, though it has since been replaced by modern solution files.

}
Go
