Latest Release
New features in UnZip 6.0, released 20 April 2009:

	• Support PKWARE ZIP64 extensions, allowing Zip archives and Zip  
archive entries larger than 4 GiBytes and more than 65536 entries  
within a single Zip archive. This support is currently only available  
for Unix, OpenVMS and Win32/Win64.
	• Support for bzip2 compression method.

Also you can make this work with Unzip 5.x if you recompile with a  
particular flag:

A separate question but: to create these I think you will want Zip 3.0:

	• large-file support (i.e., > 2GB)
	• support for more than 65536 files per archive
	• multi-part archive support
	• bzip2 compression support
I don't see either of these available for CentOS via "yum" or on Dag's  
It may or may not be trivial to compile these from source on CentOS,  
some libraries on CentOS I've noticed are rather dated.
In terms of time spent, you may wish to set up a live *BSD just unpack  
these, if that's all you need to do.  You may still end up building  
from source depending on what e.g. FreeBSD ships with, but the BSDs  
are set up with building your own items from source in mind.

Hope that helps!
