What is an .QMG file?

.QMG is Samsung Theme Graphics File

File included as part of a Samsung mobile phone theme; saves a graphic for a part of the theme (.SMT file); may be for the phone background, a button, or another visual item; compiled into a proprietary Samsung binary format.

Samsung themes are created using the Samsung Theme Designer application. When the designer exports a theme, QMG files (originally .PNG files) are compiled and packaged into an SMT file along with an XML file that specifies where the QMG files are displayed in the theme.

NOTE: Samsung Theme Designer cannot open QMG files. It can only create them.
