The program needs to be root
type in a terminal:
gksudo file-roller

then it should extract anywhere

you can use 'sudo chmod' to change permissions the command line way
but it is a very bad idea to do this for places that should only be
accesable to root

No it isn't.
the command you want is probably 'cp'.

Didn't use old DOS but I assume cp (as above).

You could also use command line tar
sudo tar -xvzf /path/to/my/file.tar.gz -C /path/to/the/folder/to/extract/to/

x = extract
v = verbose (tells you the files it's extracting)
z = use gzip compression (or decompressoim)
f = File to extrtact should follow
C = use that directory for extracting into

Hope that helps
