The file extension EMF identifies files in the Enhanced Windows Metadata format. These files can contain both vector drawings and bitmap images.
EMF is an extension of the original Windows Metafile format (WMF). While WMF supported only 16-bit data, EMF is the 32-bit version of this format. Color information is stored in RGB, CYMK is not supported.
EMF is a native Windows format and can therefore be opened by many applications. It can also be used for printer control, ie the sending of graphics data to compatible printers.
