It would seem that compression and encryption are fast becoming the best of friends. BitZipper is the latest in a line of compression applications trying to eat away at WinZip's dominance by adding high-grade encryption into the deal.
The software prides itself on its ability to deal with more compression file types than WinZip as well as 256-bit AES encryption (which can be found in WinZip 9.0). Setting up is easy enough and offers a wizard just as WinZip does. The installation is slightly less convoluted than WinZip.
