The problem nowadays is that windows seems to default to "Hide known file extensions". Which is a pain in the arse as it makes it impossible to differentiate between files. A user might never even see a file is a screensaver and not a document.
(Or as I have to deal with, 8 different files with a known and thus hidden extension with EXACTLY the same name, generated by an automatic system, but not always in the same order. And then the file options being locked by IT so I can't undo it. Good luck finding the right files after doing a few measurements...)
Biting the hand that feeds IT
