An MKV file is a type of video format. This means you can use it to encode a video or a movie, which you can then watch on your computer, or even on a portable video player or laptop. Video files are often quite large, so they are sometimes packed into a special kind of file called an archive. Examples include ZIP or RAR. These files compress the MKV file so that it is smaller and easier to transport. The catch is that you then need to “extract” the MKV file with an archive program in order to use it. Writer Bio
