I presume you mean it does in XP.

For example : this.is.a.test.com is certainly allowed : https://www.dropbox.com/sh/q6l8kc6hgo54vrw/kgImv2jue...

It shouldn't be allowed as that is how some viruses spread as Windows only see the last extension...

It is allowed, but I think it falls into the "every time you do this, god kills a baby kitten" sort of category.

And of course some punctuation has been allowed for many years (ie hyphens).

Full stops weren't originally allowed as the format for a filename was 8.3 - as soon as they had long filenames that released the full stop.

And even more significant is that this was largely following other file systems such as those used in Unix which allowed some punctuation and long filenames for years before Windows did.

The spread of viruses isn't affected by full stops. If it is looking only at the extension past the last full stop then that is exactly what it should be doing. The problem that causes the viruses (in my guess) is that Windows will hide the extension by default so when you look at a filename that you may think is a word document it could actually be an exe - most non-savvy users don't know what most of the extensions are anyway.

Indeed - which is why it shouldn't have been allowed to start with

That's basically how it works - you see something whilst Winsnooze seems something else
