The VMC file extension was also used by DESQview, a text-mode multitasking program developed by Quarterdeck Office Systems. Running on top of DOS, DESQview allowed users to run multiple DOS programs concurrently in multiple windows.
VMC files were used for DESQview video monitor configuration. This is an old, legacy file extension.
A VMC file is not a document intended for ordinary viewing. DESQview on DOS reads the file as part of its video monitor configuration, so the practical way to open it is to use it with a DESQview installation that requires it.
Modern text editors or file viewers may display the file's contents, but they are not suitable for changing DESQview's settings. Make a backup before attempting any manual edit.
There is no generally useful conversion from a VMC file to a modern format. It contains settings for the legacy DESQview DOS environment rather than transferable document data.
If the settings are needed in another DESQview installation, use the file with that installation or recreate the video monitor settings in DESQview.
