1) GZIP knows the difference in format between "compress" files, and
"ziped" files.  It will probably be subsuming the code of classic
compress Real Soon Now, so that it won't matter which program was used
to compress, GZIP can be used to uncompress it.

In short, you don't need to see the difference.

>What's wrong with the old .ZIP extension ?

Nothing.

GZIP doesn't support "multiple file archives."  That is, it is not a
direct competitor with ZIP, because it currently deals with only
single files.

The main thing that it has in common with ZIP is the fact that it uses
the same compression algorithm.

The two formats are likely to co-exist, at least for a while.
