There is only one file type that uses the .VCW extension:
eMbedded Visual C++ Workspace File
Saved workspace file created by eMbedded Visual C++ (eVC), a software development tool used to create Windows CE (Compact Edition) programs for .NET powered devices; contains layout settings for eVC's IDE; used for storing a customized project workspace during development.
VCW files can be migrated to recent versions of Visual Studio.
NOTE: VCW files are created by eVC versions 3 and 4.
