... inac mozes si dat do google napr. FAT directory structure, a mozno pochopis preco povazujem za korektne len . a .. , a vymysly MS vo Win9x povazujem za viac nez prastene.
All directories other than the root start off with . and .. entries that point to themselves and their parent directories respectively. For this reason, even an "empty" subdirectory uses one data cluster, to hold the . and .. pointers. It's important to remember that . and .. are actual entries, rather than conceptual entities; a corrupted . or .. pointer can point to anything! If .. points to zero, than that directory's parent is the root directory.
