QuickTime Player is a media player application developed by Apple. It[SQ]s capable of playing various audio and video files, including its own proprietary MOV format, as well as other common formats like MP4, AVI, and more (depending on the version and installed codecs).

While primarily associated with macOS, it[SQ]s also available for Windows (though less commonly used). Its features include basic playback controls, volume adjustment, and fullscreen viewing. Later versions have added features like screen recording and basic editing capabilities. However, it[SQ]s not generally considered as feature-rich as other media players like VLC or Windows Media Player.
