PowerArchiver

PowerArchiver is a backup utility with hundreds of features, yet remains easy to use, small and fast. Novice users will find a familiar interface complete with tutorial and detailed help, while more experienced users can take advantage of full Explorer integration, multiple encryption methods and advanced compression algorithms.

PowerArchiver includes full support for Microsoft's newest operating system, Windows Vista. User Account Control and new Vista dialog windows such as New, Open and Save are supported. You do not need to worry about compatibility problems with PowerArchiver if you are using or considering upgrading to Vista.

New, Modern User Interface

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.

For those that desire the older look, PowerArchiver's Classic interface is still available.

Superior ZIP Support

PowerArchiver offers superior ZIP format support compared to other archivers. Here are the highlights:

• Support for unlimited file size and unlimited number of files in ZIP archives
• Support for advanced Deflate64 method providing higher compression ratios
• ZIP AES support (both PkZip 5.1 and WZ 9.0 standards supported)
• Fast and strong compression and decompression
• Multiple disk spanning, with support for unlimited span sizes

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."
