MKV

MKV (Matroska Video) is a versatile digital container format that holds various multimedia files, such as video, audio, subtitles, and other data, bundled into a single file. It supports high-quality, high-definition content and allows for multiple audio tracks or subtitles within one file, making it popular for movies and videos. MKV is open-source, meaning it's freely available for developers and users, and is compatible with many media players. Essentially, MKV acts like a digital folder, organizing different types of media into one convenient file while maintaining high flexibility and quality.
