WMF (Windows Media Format).
Microsoft’s proprietary compressed streaming audio and video format that competes with MP3/MP4 and
RealAudio. JMF (Java Media Framework) does not support it. It has a *.wma extension. Confusingly,
*.wmf is a vector graphics metafile format, nothing to do with audio or Windows Media
Format. Microsoft claims that wma files have CD (Compact Disk) quality with double the compression of
WMF (Windows Metafile Format).
Microsoft’s proprietary vector graphics format that permits embedded raster graphics. It has a similar
function to PostScript to provide a printer-independent format for storing files to be printed. Like
PostScript, they can contain executable code.
