html vs htm

Can you please tell me what is the difference between an html file and an htm file?

I think they are the same thing, just something to do with different things reading them. I could be wrong though, let someone in the know tell you

I am not one who is "in the know", but I do know how to use google.

Searched for "htm vs. html"

Found this answer within the first few links.


I hope that is actually correct information and that it helps you.

html is one letter longer than htm. period. it really doesn't matter which method you like.

You could name a file with a .htm, .html, .rob, .kook, .foo, .bar, .page, or a .artypay extension; it does not matter.

uknightuss's link does have accurate information, or I would hope so, because I was the last person to edit that.

You can't name it anything. I'd suggest sticking to extensions that aren't already associated with most peoples machines (ie. .swf, .exe, .txt).

It's excactly the same. Just like .jpeg and .jpg...

A bit ago I wrote a script which you gave a url and it would take whatever file the url was and write it into server space with a .bmp extension. if the file requested was a html file, it ended up displaying the html code rather then having an error reading the image. If it was another type of extension it would have that read error.
So, I guess you have a lot of freedom with this sort of thing...

I would suggest that too, but it doesn't mean you can't. File name is unimportant to browsers (that work), if the correct Content-Type header is sent out. Only the content-type header matters. IE excepted -- it tries to figure out the contents of files by looking inside the file, in some cases. This has caused some security vulnerabilities in the browser.

How many people actually use content type headers...

People? It's a matter of what browsers do.

I use to name my pages with .lteam extention and they work fine!

But I would suggest to name'em by their very own extention.

I just wanted to be original! but you can do anything you want really!
