htm & html

what different?

[Jsuper]

.htm & .html
Are there any differences between these two files?

Thanks.

.htm is simply a short version of .html, used back when there were still a lot of computer opereting systems in use that limited filetypes to three letters.

The content of both filetypes is identical.

My English isn't very well. I guess your meaning is the difference is in OS support.
some of OS can only run 3 letters filetypes.
right?

Jsuper,

Yes. The difference is in OS support.
Some old operating systems can only use 3 letters filetypes.

This now only matters if the files need to be *saved* to an old computer using FTP. All modern browsers can display the pages, regardless of the filenames in the URL.

I understand. The difference between jpg & jpeg is also like this.
Thank you Jim!

Thank you T_T
It's very kind of you.

Now that .htm is suit for any OS or Browser, why .html was born?

[Farix]

.html came first.

Even back in the days when the home computer OS could only use 3 letter extensions, once the file had been uploaded to the web server using FTP, the filename could then be altered to have the full four-letter extension instead. Most people never seemed to realise that that could be done.

[Jsuper]

Oh? did any file have 4 letters extensions?

[g1smd]

Yeah, the original web users used .html and .jpeg etc.

Some of the FTP client softwares can automatically change the file extention .htm into .html or .jpg into .jpeg or whatever you want when you upload the webpages file. But they all are right, that file format mostly be used on 8.3 filename format but Unix family has long changed that 8.3 file format.
