Answered: Does changing filename extension work?

You may hear from others many times that one can change the filename extension directly if he wants to convert MP4 to M4A. But is it true? Before we continue, it is worth mentioning that most media players nowadays would recognize and play a file through the media data it contains rather than its filename.

To give an example, if you have an MP4 video, and change ".mp4" to ".m4a", when you try to play it on JoyoPlayer, Windows Media Player, or VLC media player, you can still hear the audio while watching the video. Most importantly, when you check the file sizes of the two files (one is the MP4 video you already have, and the other is the M4A file), it turns out that they are almost the same.

However, if you use Joyoshare Video Converter to convert MP4 to M4A, you would find that the file size of the M4A file is much smaller than that of the MP4 video. What's worse, if you have an MP4 player as well as a collection of MP4 videos, but you intend to save them into M4A format because you only want the audio parts, adjusting filename extension makes no difference, except the consequence that too much storage space will be wasted. To sum up, changing the filename extension actually doesn't work as you expect.
