How to read this

  • An extension is a label, not the contents. Rename a file to .png and if the bytes inside are JPEG, it is still a JPEG.
  • A MIME type is how the internet names a file kind. Browsers look at that value, not the extension, to decide whether to display or download.
  • A MIME type starting with x- was never registered as a standard. Plenty are in wide use, but they are not official names.
  • Video extensions name a container. The same .mp4 may play on one device and not another, depending on the codec inside.

Frequently asked questions

Q. What is a .wma file?

It belongs to the audio category and its MIME type is audio/x-ms-wma. The contents are binary, so opening it in a text editor shows garbage.

Q. What opens a .wma file?

Windows Media Player, VLC all handle it. In a browser it does not display — the browser downloads it instead.

Q. What is the MIME type of .wma?

audio/x-ms-wma. The first half, audio, names the broad kind; the second half, x-ms-wma, names the exact format. It starts with x-, which means it was never registered as a standard.

Q. Can I convert a .wma file to another format?

Yes — open it and re-save through a converter. Renaming alone changes only the label; the bytes stay put, and programs that check the real format may refuse to open it.

Q. My .wma file will not open.

First check that Windows Media Player is installed. If it still fails, the download may have been cut short, or the file may only be named .wma while holding a different format inside.
