I came from Windows 2 years ago and I knew there were hidden files in all OS's. As Windows has the simple option to show them to you, I supposed that if I contacted Apple support they would tell me how to show hidden files. But they simply told me they didn't exist at Mac OS. So I had to find the answer myself.
But today I was browsing some files with the terminal, I did
ls -l -a to see all files (including those hidden) in a list and I saw kind of a different file that began with a dot and an underscore (
._). I could see in the Finder all files except that one.
So my question is: Why can't I see that file (e.g.
._hello) in the Finder if I have already configured it to show me all files, including the hidden ones? Is that another kind of hidden file which I'm not aware of?
