So what's the high level problem? *Why* are you trying to hide file
names or directories?
I repeat, is this for a university problem set or project?
Or is there a practical real-life use for it. If so, *what* is the
practical real-life use? What are you trying accomplish at the high
level, and why is it useful to try to hide filenames or directories?
Is this for a root kit, where you are trying to write malware?
