I want to set up a limited acct for my teenage daughter as
well as an admin acct for myself. In general I know how to
do that, incl requiring password for me. But once I do
that, I also want to ensure that my daughter cannot even
SEE a list of ANY of the files I have installed on my part
of the hard drive. I know that I can make it so she can't
view them, use them, delete them, yada yada yada. What
I'm saying is this: I don't want her to even be able to
use Explorer, for example, or any other means available to
her, to EVEN DISPLAY A DIRECTORY TREE LISTING OF THE FILE
NAMES I HAVE ON MY PART OF THE HARD DRIVE! Is this
possible? If so, how? Does simply making files or
folders private do that? Not to beat a dead horse, but
let's say, just for the sake of argument, that I download
and save a file called (&(&()&()*&%$^.jpg with an
embarrassing filename I don't want her to read, for
whatever reason. How can I save that file to some part of
the hard drive where she not only cannot LOOK at the file,
but also cannot even KNOW it's there?!
