.SMF File Extension

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

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

NOTE: Apache OpenOffice was formerly known as OpenOffice.org.

Serif discontinued PagePlus and replaced it with Affinity Publisher in 2017. Serif also discontinued DrawPlus in 2015. The last version of the software was X8.
