When I right-click a .uv2 file in the Windows Explorer, the custom options in the Context Menu which pops-up are 'Open' and 'DCI' What is 'DCI'?? The command line is:
uv2.exe -i "%1"
DCI stands for Development tool Communication Interface. This is an upcoming interface for UML tools. It will come in one of the next releases of uVision2, but is already installed for future compatiblity.
