This file.(admin)
@assoc .cbp="cbp" >nul
@ftype cbp="%~dp0CBLauncher.exe" "%%1" >nul
@assoc .c="c" >nul
@ftype cpp="%~dp0CBLauncher.exe" "%%1" >nul
@assoc .cpp="cpp" >nul
@ftype cpp="%~dp0CBLauncher.exe" "%%1" >nul
@echo done.
@pause> nul


Then I click on new file.cpp.

From what I understand, create a project and add it to this newly created project.
