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?
