Make a habit of dropping the tar file into the home directory. Linux is meant to work this way, nothing lies around. Do su - into root. cd into /home/user, then ls shows the content. Do tar -xf <file as you see it there>, the correct directory will be created and all installed as needed. Usually into /usr/local, icons will be somewhere in /usr/share.
