File Type:7z compressed archive file
Category:Archive and compressed file
File Description:7z is the new backup, archive - compressed file format, providing high compression ratio.

The main features of 7z format:

- Open architecture
- High compression ratio
- Strong AES-256 encryption
- Ability of using any compression, conversion or encryption method
- Support for very large files with sizes up to 16000000000 GB
- Unicode file name support
- Solid compression ratio
- Archive headers compression

7z has an open architecture, so it can support any new compression method, too. The following methods currently are integrated into 7z:

LZMA Improved and optimized version of LZ77 algorithm
PPMD Dmitry Shkarin's PPMdH with small changes
BCJ Converter for 32-bit x86 executables
BCJ2 Converter for 32-bit x86 executables
BZip2 Standard BWT algorithm
Deflate Standard LZ77-based algorithm

LZMA is the default and general compression method of 7z format. The main features of LZMA are:

  • High compression ratio
  • Variable dictionary size (up to 4 GB)
  • Compression speed: about 1 MB/s on 2 GHz CPU
  • Decompression speed: about 10-20 MB/s on 2 GHz CPU
  • Small memory requirement for decompression (depend from dictionary size)
  • Small code size for decompression: about 5 KB
  • Supports multi-threading and P4's hyper-threading

The LZMA compression algorithm is very suitable for embedded applications. LZMA is released under the terms of the GNU LGPL.

7-Zip supports encryption with the AES-256 algorithm. This algorithm uses a cipher key with a length of 256 bits. To create that key, 7-Zip runs a derivation function based on a SHA-256 hash algorithm. A key derivation function produces a derived key from the text password entered by the user. To increase the cost of an exhaustive search to crack a password, 7-Zip uses a large number of iterations when it produces a cipher key from a password.

7z is part of the 7-Zip program distributed under the GNU LGPL.

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

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

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."

Multiple Formats Support Including ISO

PowerArchiver has native support for most popular compressed and encoded formats currently in use. All formats are fully integrated into PowerArchiver, so you can utilize all PowerArchiver tools with each of them.

  • Read and write support for ZIP, 7-ZIP, CAB, LHA (LZH), TAR, GZIP, BZIP2, BH, XXE, UUE, yENC, and MIME (Base 64)
  • Read and extract support for: RAR, ARJ, ARC, ACE, ZOO plus ISO, BIN, IMG and NRG disc image formats
  • Brand new Plug-in System enables new formats and file types to be supported with a small download.

Linux operating systems

Company / developer:
  Linux Online Inc.


Linux is an operating system that was initially created as a hobby by a young student, Linus Torvalds, at the University of Helsinki in Finland. Linus had an interest in Minix, a small UNIX system, and decided to develop a system that exceeded the Minix standards. He began his work in 1991 when he released version 0.02 and worked steadily until 1994 when version 1.0 of the Linux Kernel was released. The kernel, at the heart of all Linux systems, is developed and released under the GNU General Public License and its source code is freely available to everyone. It is this kernel that forms the base around which a Linux operating system is developed. There are now literally hundreds of companies and organizations and an equal number of individuals that have released their own versions of operating systems based on the Linux kernel. More information on the kernel can be found at our sister site, LinuxHQ and at the official Linux Kernel Archives. The current full-featured version is 2.6 (released December 2003) and development continues.

Apart from the fact that it's freely distributed, Linux's functionality, adaptability and robustness, has made it the main alternative for proprietary Unix and Microsoft operating systems. IBM, Hewlett-Packard and other giants of the computing world have embraced Linux and support its ongoing development. Well into its second decade of existence, Linux has been adopted worldwide primarily as a server platform. Its use as a home and office desktop operating system is also on the rise. The operating system can also be incorporated directly into microchips in a process called "embedding" and is increasingly being used this way in appliances and devices.

Throughout most of the 1990's, tech pundits, largely unaware of Linux's potential, dismissed it as a computer hobbyist project, unsuitable for the general public's computing needs. Through the efforts of developers of desktop management systems such as KDE and GNOME, office suite project and the Mozilla web browser project, to name only a few, there are now a wide range of applications that run on Linux and it can be used by anyone regardless of his/her knowledge of computers. Those curious to see the capabilities of Linux can download a live CD version called Knoppix . It comes with everything you might need to carry out day-to-day tasks on the computer and it needs no installation. It will run from a CD in a computer capable of booting from the CD drive. Those choosing to continue using Linux can find a variety of versions or "distributions" of Linux that are easy to install, configure and use. Information on these products is available in our distribution section and can be found by selecting the mainstream/general public category.

The Unarchiver

The Unarchiver is a much more capable replacement for "", 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
