If packed with Gzip, you always have to unpack it in order to read the 
content.

Tar is the container and Gzip does the compression. So the files in a 
tar.gz file are first put into a container then packed. So in order you 
read anything inside the tar you have to unpack the file to have access 
the tarball to read your file inside.
