7 - Zip
It's easy for Windows users to forget that WinZip isn't the only file-compression utility in the world. Like its better-known competitors, the free 7-Zip unpacks a host of archive formats, including ZIP, TAR, GZ, and its own 7z format. Unlike WinZip, though, it can create TAR and GZ archives, which are commonly used on Unix and Linux systems.

E- Sword
e-Sword is a fast and effective way to study the Bible. e-Sword is feature rich and user friendly with more capabilities than you would expect in a free software package. The fact that e-Sword is free is just one of the blessings and does not speak of the quality of the software. I make my living writing software and I believe I have put forth my best effort in this endeavor. The real work, however, was put in by the godly men and women who devoted countless years creating the texts that have been made available for our benefit. (Freeware)
