Show Hidden Folders -

For new users, hidden folders are a source of confusion and anxiety. “Where did my AppData folder go?” “Why can’t I see my Library on Mac?” The operating system decides that certain directories— /System on macOS, C:\Windows\System32 on Windows, ~/.config on Linux—are better left unseen.

Apple has already made the ~/Library folder hidden by default in macOS (since Lion in 2011). But they also added that Cmd+Shift+. shortcut—an acknowledgment that power users still need access. Microsoft continues to treat hidden files as a second-class citizen, often excluding them from search results unless forced.
