Blend1 remove file association

How to remove file associacion for blend1? Now it’s looks like regular blend file.

Why would you not want to have that association? That will only make it harder to open them when you need to, no?

I imagine if one was to opt to not show extensions this could cause some confusion as to which file to open. Not that there are no ways around that, but still…

Because I get confused all the time, and I lose my saves.
