what is the best/easy way to erase files
I have a new PC and need to rid of my old PC.
While I don't have much confidential stuffs in it,
and the computer probably will be hacked by
my geeky brother-in-law, I do want to securely
erase my stuffs. What is the best/easy way to
do this? Use shred? I only need to erase a
few directories, i.e.,
or reformat the disk or what? Don't want to do too
much works or figure (learn) what to do too much.
