Have you encountered a problem with a VMC file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a VMC file here. In the further part of this page we have added a list of programs that should open your VMC file. It is enough you choose a proper application for your operating system, download and install it.


The file extension VMC is used for configuration files of the emulation software Windows Virtual PC. Windows Virtual PC lets you set up Windows 7 virtual machines (VMs) running Windows XP or 98, for example.

VMC files include settings in an XML-based format. The settings include, but are not limited to, the name of the VM, the amount of memory the VM will use, and the location of the disk file (extension vhd) where the operating system is installed.

Usually the VMC files with the vhd file (Virtual Hard Drive) are in the same folder. Windows Virtual PC is the successor of Virtual PC 2007 and is only available for Windows 7. However, Virtual PC 2007 also uses VMC files for configurations that may not be compatible.

Windows Virtual PC can create shortcuts (file extension vmcx) that point to a specific VMC file. Double-click on a vmcx file to start Windows Virtual PC directly with an assigned configuration. The emulation software VMWare can import a Virtual PC VM via the VMC file and convert it into a VMWare own format.

VMC files are also used by Virtual Server.

How to open a VMC file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the VMC file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a VMC file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support VMC files. At this point we are looking for disk space where the application was installed in and we can link it with a VMC file. Since then, our operating system will use the selected program to support all VMC files.

Other issues

Despite the described problem with VMC there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the VMC file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the VMC file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
