PeaZip is a Open Source packer that supports many formats, much like any other packer out there. The most command formats like zip, rar, ace, 7z are handled but also many lesser used ones like bz2, upx and cab. The user is asked during installation which context menu items he wants to add which is very user friendly. Most packers simply add their entries to the context menu even if the user would never use some of the options.
IZArc a great universal archiv software
If you are looking for a universal archiv software other than 7-zip you should take a closer look at IZArc which lately replaced WinRar on my computer. The real beauty of IZArc is of course it’s support of most known archiv formats such as zip, rar, 7-zip, gz, ace, tar and dozens others including formats such as iso, bin and nrg.
