I have some media content consists from m2v(video) + wav(audio) files. I want to find more information about this media format.
How to play this media in players?
Does the name of file with video (_name_.m2v) always match the file with audio (_name_.wav)?
Do the files have any metadata with information about other related files? (for example, does the .m2v file has information about .wav file)?

m2v is an MPEG 2 elementary stream (raw MPEG 2 video). WAV is usually uncompressed PCM audio (though the WAV container does support compressed audio too).
Some players can be set to automatically load an audio track with the same name as the video. Or you can mux the two together into an MPG, MKV, etc. file. Then any player will automatically play audio and video.
No metadata in m2v. WAV can contain metadata.
Thank you for the reply.
Could you please describe which type of metadata about relation with m2v stored in wav? Maybe you can give link to the some standard where described this information?
Parts 2 & 3 will be of help. The use of Groove, which came with my version of Windows 10, was something I did not know.
It's available in the Microsoft Store.
The relationship between m2v and wav, I don't know. I assume it's just two tracks. Multiplexed, they could be put in most containers. avi, mp4, mkv, ???

Thanks everyone for the replies. To clarify my task. I'm programmer and I need to write file watcher to detect media in forlder.
In the m2v + wav case I need to unite this files to bundle. So I need to determine what m2v and wav files includes to 1 media. Now I'm trying to do this only by filename. I'm taking m2v filename as prefix and finding depends wav files. Is it right way?
DgIndex produces a pair of files like:
VTS_01_1.demuxed.m2v VTS_01_1 T80 2_0ch 192Kbps DELAY -51ms.ac3
