BitZipper
BitZipper is a Windows utility that lets you open Zip files, Rar files and other compressed archives (also called compressed folders, WinZip files, WinRar files) with ease. It can open every kind of compressed or encoded file you are ever likely to encounter, including the most popular types: Zip, Cab and Rar. It lets you create files in most of these formats, too. BitZipper is truly the Swiss Army Knife of archive managers!

Whether you're a computer novice or a power user, BitZipper is easy to use. For the novice, there's a wizard that can walk you through the stages of whatever you want to do. The wizard helps you to open a zip file (and other compressed files), create new zip files, or back up your files to a compressed archive.
For the more experienced user, BitZipper has a "classic" user interface that lets you open or create compressed archives, and add, extract or remove files, using the menu or toolbar, or by drag and drop.

BitZipper has many powerful and unique features for the power user. It allows you to install software directly from a compressed archive without first extracting the contents to a folder. It can split archives into multiple volumes that will fit onto floppy disks or other media. It can convert archives directly from one format to another.
BitZipper can also create self extracting archives. These are .exe files that can extract their contents on another Windows computer without the aid of any archive manager.
You can also use BitZipper as a backup application. You define a backup set by specifying which files you want to include or exclude, and save it. To protect your data, backups can be encrypted (BitZipper can use uncrackable 256-bit AES encryption.) You can then back up those files any time you want, by selecting that backup set. BitZipper will even create an icon right on your desktop to perform a one-click backup of your data.
BitZipper is a tool you will use every day not just to open Zip and other archive files downloaded from the Internet, but also to back up, archive and protect the valuable files on your computer.
