Isn't it just great how a decision made by some genius in Microsoft decades ago caused so much confusion and mess. Even on Windows 11 the default is to hide extensions, because, geez, wouldn't want to confuse people with change after decades of it being like that.

The idea of the last part of the filename (after the period) determining what program is launched to handle the file is odd anyway...

I wonder if the Windows spyware infrastructure measures what % of people turn off extension hiding..

Nope. It had been renamed from .avi. CP.
