I wrote some codes to create a directory named "E:\hkhkhkhk\...." in c++. It actually created "...." iteratively. And the parent directory "hkhkhkhk" cannot be removed.
I was wondering how the system explains "....".
The code is as below, execute it in virtual machine.
#include <windows.h>
#include <iostream>
using namespace std;
int main()
{
if (!CreateDirectoryA("E:\\hkhkhkhk\\....\\", NULL))
cout << GetLastError() << endl;
getchar();
return 0;
}

Windows doesn't allow programs to use paths ending with a dot; whenever a program tries to access such a path, all dots are quietly removed from the end.
You bypassed this restriction when creating the directory since your path actually ends with a backslash, but other programs (e.g. Windows Explorer) don't do this.
So when you double-click the directory in Explorer, it tries to change to E:\hkhkhkhk\.... but actually gets E:\hkhkhkhk\ (which is the same as the parent directory), creating the illusion of infinite recursion when in reality you never go anywhere at all.
