.SMF File Extension

Formal MIDI file specification developed by the MIDI Manufacturers Association; similar to a .MID file.

Vector image created in the Serif Metafile (SMF) format, a proprietary format that extends the Windows Metafile (WMF) format to include better line, fill, and text definitions; used for sharing vector graphics between Serif applications, including DrawPlus, PagePlus, and WebPlus.

Math formula created by OpenOffice.org (OOO) and other variants of the office suite; stores the syntax and formatting of a mathematical equation or expression; replaced with the newer .ODF format, but is still supported by OOO.

NOTE: The SMF format was originally used by StarMath through StarMath version 5. StarMath 6 and OOO version 1 adopted the .SXM format, which was then replaced by the OpenDocument ODF format. OOO still supports the SMF format even though it has been deprecated.

Project file created by SkinMagic C/C++ Toolkit, a developer program used for creating application interface skins; can contain user interface dialogs and bitmap graphics that are used for overlaying components (buttons, borders, etc.) of the interface.

SMF files are created by a program called SkinMagicBuilder, which is included in the SkinMagic C/C++ Toolkit installation.
