Not necessarily so. Perhaps "gunzip figures.tar.gz" followed by "tar -xvf 
figures.tar" works out all right.

I think some earlier version of tar or gzip didn't handle the situation 
correctly when piping between them. However one by one it worked anyway.

Or are you sure that there ought to be more files in the archive file?
