Thank you. Now my primary system is currently Windows 10, since sine Windows uses the "h" attribute to hide files I should (I guess) sort out of butler takes this into account, although in my many years that I was a Mac user and thus in a Unix environment I've gone to like the Unix approach to many things more... All my own programs consider the . prefix as hidden now, but that doesn't mean others follow suit.
Since I guess butler was written in Go if I wasn't mistaken, I guess it will work the same in Windows.... Thank you for trying this out for me ;)
