The Unarchiver

The Unarchiver is a much more capable replacement for "BOMArchiveHelper.app", the built-in archive unpacker program in Mac OS X. The Unarchiver is designed to handle many more formats than BOMArchiveHelper, and to better fit in with the design of the Finder. It can also handle filenames in foreign character sets, created with non-English versions of other operating systems. I personally find it useful for opening Japanese archives, but it should handle many other languages just as well.

It is very simple to use and install - simply copy it into your Applications folder or whereever you prefer, and then set archive filetypes to open using it. This can either be done the usual way, or by double-clicking the icon to show The Unarchiver's preferences.

Supported file formats include Zip, Tar-GZip, Tar-BZip2, Rar, 7-zip, LhA, StuffIt and many other more or less obscure formats

You do not need to worry about compatibility problems with PowerArchiver if you are using or considering upgrading to Vista.

A completely revamped user interface in PowerArchiver makes it easier to access the wealth of features that PowerArchiver has. This task-based interface utilizes the same "Ribbon" design found in Microsoft Office 2007, and ensures you qick access to the most used features while not hidding others under layers of menus.

7-Zip Compression

7-Zip is an advanced compression format featured in PowerArchiver. It is an open source format, providing an open architecture and high compression ratio. 7-Zip outperforms ZIP, ACE and even RAR in many tests. However, 7-Zip's greatest strength is that it is not controlled by any organization or individual, but by an open source LGPL project to which anyone can contribute. More information on 7-Zip and its superior compression can be found at 7-Zip.org.

PowerArchiver introduces a new Transparent Update feature for 7-Zip archives, which allows you to quickly add or remove files even if the archive is "Solid."
