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'.

DON'T

as above

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
