The correct file extension for markdown files is:
That is all. No others.
Make it so!
Update: It seems the GitHub
.md extension is becoming canonical for those who prefer shorter file names. And Dr Drang @drdrang uses it. Who am I to argue. But I’ll be sticking with
I suppose I’d better say why:
- We no longer live in a 8.3 world, so we should be using the most descriptive file extensions. It’s sad that all our operating systems rely on this stupid convention instead of the better creator code or a metadata model, but great that they now support longer file extensions.
- Markdown is text but text is not markdown. It’s a few seconds work to associate an application to edit text and another to edit markdown files, so use that. I use different editors for them, so its best to help the operating system here.
- (No longer applicable)
.md(a.k.a the GitHub extension) could be mistaken for GCC Machine Description files, confusion is bad, don’t do it.
- All the others are just shortened forms on the canonical
.markdown, so use the canon. Avoid
.mdnor even the horrible
- If you have made the mistake in the past of using the wrong file extension, write a script to rename the old files now. Ok, now run it. Good. Problem solved.
