What is an MKV file?

MKV files mostly belong to VLC by VideoLAN. MKV is the filename extension of video files saved in Matroska multimedia container format. A file with MKV filename extension may contain several video tracks (in most cases only one), as well as several audio and subtitles tracks saved in various formats. An MKV file may also contain images (such as album art), and file meta data. MKV files support various video and audio codecs and may be converted to other video formats. This file type is typically used to save High-Definition videos of Television shows, full-length movies, and short videos.

How to open MKV files

Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert.
