Files with the extension .MTF are 'theme' files for use with 'Motorola' cell / mobile phones. .MTF theme files are used to customise the look of the Motorola phone and include a wallpaper, a screensaver and a ringtone combined into one dataset. So the .MTF dataset contains: * Screensaver - an animated image covering the entire screen that plays when the handset is idle. * Wallpaper - a graphic adorning the screen's working area that might be a personalized image or company logo. * Ring tone - this could be a customized short unique sequence of sounds, or brief interval of MIDI music.
