Neither the root directory of a volume does. But that is irrelevant to the
issue.

I don't care how an OS-specific search might work. That is actually the
reason why I use Ada.Directories, which abstracts any concrete OS. So the
question is whether appearance of ".." is a requirement. Maybe, ".." is an
alias name? But then

1. Why there is no File_Kind value for aliases?

2. Why Full_Name of the Directory_Entry corresponding to ".." does not
render the true name of? Can the same file have different full names?
