'''Enhanced Metafile''' ('''EMF''') is a vector graphics format native to 32-bit versions of Microsoft Windows. It is the successor to [[Windows Metafile]] (WMF).

There is an extension of the format, named '''Enhanced Metafile Format Plus Extensions''' ('''EMF+''').

The '''.emz''' filename extension is reportedly used for [[gzip]]-compressed EMF files.

== Format details ==
Though EMF is very similar in concept to [[Windows Metafile|WMF]], the format itself is quite different, and completely incompatible. It has a different record structure, and different command opcodes.

== Identification ==
EMF files begin with bytes {{magic|01 00 00 00}} (representing record type EMR_HEADER), and have ASCII "<code>&nbsp;EMF</code>" (with the leading space) at file offset 40.

EMF+ files are EMF files with the following characteristics. Let ''n'' be the 32-bit integer at offset 4. At offset ''n'' is the 32-bit integer 0x00000046 (representing record type EMR_COMMENT). At offset ''n''+12 is the ASCII string "{{magic|EMF+}}".
