public removeAll() as Void throws IOException
Recursively removes the folder content and the folder itself.
The parent folder is never removed, even when it becomes empty.
Paths built from a parent-traversal segment (..) are rejected even after path normalization, preventing an accidental deletion of an ancestor directory.
parent = FolderPath(Path.tempDir, "klyn-example") child = FolderPath(parent, "child") child.mkdirs() child.removeAll() assert parent.exists assert not child.exists
