MKVToolNix 75: MKVToolNix is a free application for editing MKV files.
With the free app you can cut a large file into smaller pieces, or vice versa to join smaller pieces to a larger one. You can save the sound of MKV to Mp3 but also embed subtitles very easily.
It's a very practical tool for those who have HD movies on their PC and want to edit them.
