A file that contains other files. It generally refers to graphics files that can hold vector drawings and bitmaps. For example, Windows Metafiles (WMFs) and Enhanced Metafiles (EMFs) can store pictures in vector graphics and bitmap formats as well as text. A Computer Graphics Metafile (CGM) also stores both types of graphics. See Windows Metafile and CGM.

Container Formats

A metafile that can hold a variety of audio and video formats or any mix of audio, video and text is often called a "container." For example, AVI, MPEG and Ogg are A/V container formats. See AVI, MP4 and Ogg Vorbis.

Metafile is a generic term for a file format that can store multiple types of data. This commonly includes graphics file formats. These graphics files can contain raster, vector, and type data. A common use for these files is to provide support for an operating system's computer graphics; e.g., Microsoft Windows uses Windows Metafile, and Mac OS X uses PDF.

Some examples:

(PICT) Macintosh PICT resource, superseded by PDF in Mac OS X
(WMF) Windows Metafile = (EMF) Enhanced Metafile
(EPS) Encapsulated PostScript
(CGM) Computer Graphics Metafile
(PDF) Portable Document Format
(CDR) Corel Draw File
(SVG) Scalable Vector Graphics
