>FWIW, I consider that setting ("hide known extensions") in Windows to be a terrible idea. It's one of the first things I change anytime I install any version of Windows.

Its not a bad idea, just annoying to people that deal alot with files directly like us (the minority).

It would be nice if there was a general control panel in Windows to be able to set all these I've-been-a-computer-user-for-years-and-this-is-how-it-has-to-work-damnit settings.
