The rar example was pretty random because I encountered that once. Also, I have t admit that I also know windows users who haven’t got the tiniest clue what they are doing. I just feel like it’s even worse on mac because the OS is more oppinionated and tends to hide even more complexity from its users without actually solving it. Windows also has got some horrendous default settings btw., e.g. hiding file extensions in explorer and searching through documents content when using the explorer search bar.
