IZArc is a freeware archive utility that can zip and unzip files in a wide range of formats. IZArc2Go is a fully portable version of IZArc. It does everything the installed version does, although you can't integrate it with right-click menus in Explorer or associate it with any archive file type.
We downloaded the program's installer, which extracted the executable file and other files to a folder in our Downloads directory by default. Since the program is portable, you can save these files anywhere, including a USB drive or other portable device. We clicked IZArc2Go's program file, and the familiar IZArc interface opened. If you've never used a third-party WinZip/WinRar replacement, IZArc2Go is fairly typical, with the usual menu bar, toolbar, main window, and left-hand navigation panel. The program advised us to click New to create a new archive or Open to open an existing one. We clicked Open, browsed to a zipped folder, selected it, and clicked Extract from a menu that also let us Add, Open, and Test archive files. The Extract dialog offers more choices than the standard Windows tool, such as the ability to restore file attributes and confirm file overwrites. After we'd extracted some zipped files, we created an archive file using a similar process. IZArc2Go supports most archive file types, including 7-Zip, RAR, TAR, TAZ, CAB, DEB, and many others, and it opens CD image files such as ISO, BIN, CGI, and NRG. To uninstall the program, we just deleted its folder. A clear, businesslike Help file explained things satisfactorily.
Perhaps the best thing about third-party zip tools like IZArc is that they let you simply right-click a file and select the tool from the Windows context menu. Obviously, that's not possible with IZArc2Go. However, it does everything else you're likely to need in a portable archive utility.
