What is the .MKV file type?

The .mkv file extension is associated with video files (the last "v" of the .mkv file extension stands for video). MKV files follow specifications of Matroska Multimedia Container, which is a free container format for audio-visual information. MKV may contain any number of tracks: audio, video, subtitles, pictures. MKV is typically used to store movies and TV shows, including HD movies (high definition video). It is possible to save the entire contents of a DVD or Blu-ray disc in a single MKV file.

MKV files may be quite big, especially the ones containing multiple high-quality audio tracks, Full HD video, and other elements.
