What is a VMC file?

VMC files mostly belong to Windows Virtual PC by Microsoft. VMC is the extension for a Windows virtual machine configuration file. It is used by Windows Virtual PC. Windows Virtual PC is a virtualization software that allows running applications in a virtual machine. The virtual machine can run supported Windows operating systems. Starting with Windows 8, Windows Virtual PCwas superseded by Microsoft Hyper-V. VMC is a configuration file that stores the settings required to launch a virtual machine. The file is in an XML format and contains information such as as the name of the virtual machine, allocated memory, the locations of other machine files, and network settings. The actual data for the machine is stored in virtual hard disk (VHD) files, and its runtime state is stored in virtual machine saved state (VSV) files. VMC files also store references to virtual machine undo drive (VUD) files if the Create Undo Disks option is enabled for the machine. A shortcut to the VMC file is also created by Windows Virtual PC. This shortcut file has the VMCX extension.
