229 - 7zip

7-Zip is an amazing compression program. Compression ratio results are very dependent upon the data used for the tests. Usually,
7-Zip compresses to 7z format 30-70% better than to zip format. And 7-Zip compresses to zip format 2-10% better than most of
other zip compatible programs.

1. You can search rpm if you want

 URL- http://rpm.pbone.net/

2. Copy the link and use it to rpm comand with "-ivh"

# rpm -ivh ftp://ftp.sunet.se/pub/Linux/distributions/fedora/epel/epel/testing/5/x8...

# rpm -ivh ftp://ftp.sunet.se/pub/Linux/distributions/fedora/epel/epel/testing/5/x8...
