MOV is a digital video file format developed by Apple for use on their QuickTime multimedia platform. The format is commonly used for storing and sharing high-quality video content, as well as for editing and authoring video files.

MOV files can be played back on a variety of media players, including Apple's QuickTime Player, as well as on other media players that support the H.264 and AAC codecs. The format can also be converted to other more widely supported video formats like MP4 or AVI using compatible media conversion software. Overall, MOV is a useful video file format for storing and sharing high-quality video content, particularly for Apple users who want to take advantage of the QuickTime multimedia platform and its associated tools and features.
