`Path.Parent()` leading to bad state

[osgo]

I don't think you would really want Parent to behave like backspace. The Shell hierarchy contains infinite cycles and other oddities which would make writing scripts more complex, not less.

But does pressing Backspace ever lead to infinite cycles? You could call the function like path.Parent("s"). I was up to behavior like going up in the folder tree. For backwards compatibility alone, you couldn't make this the new default behavior, of course.

If I understand correctly, couldn't infinite cycles only happen when going deeper into the tree and not when going up?

@Leo

If you're using aliases and want to get the parent of what the alias points to, you need to call Path.Resolve before Path.Parent.
