What is an enhanced metafile (EMF file)?
An enhanced metafile is a 32-bit metafile that can be used by 32-bit versions of Windows (95, 98, Me, NT, 2000, XP and Vista) to display a picture. An enhanced metafile can contain a much broader variety of commands than a “regular” Windows metafile. Basically, the enhanced metafile format is a 32-bit super-set of the 16-bit Windows metafile format.
