.QMG File Extension
File TypeSamsung Theme Graphics File
What is a QMG 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.
