7-Zip是一个开放源码的数据压缩程序,主要用在Microsoft Windows操作系统,Unix-like的操作系统如Linux与FreeBSD下面有7-zip的移植版本p7zip可以使用。ZOl提供7zip中文版下载,7-zip正式版官方下载安装。

7-Zip是一款GNU/LPGL协议下分发的免费软件,可以说是目前最有希望成为zip、rar之后的下一个主流压缩格式的文件压缩格式了。7zip的压缩率是他最大的竞争优势,在选择普通压缩率的情况下我们已经可以轻松击败winrar的最高压缩率了。但是7zip也不完美(要是完美了,RAR就已经被取代了),主要是软件的界面依然不够优秀,格式本身对于分卷压缩的支持也不好,但是这不妨碍7zip成为最有潜力的压缩格式。

7-Zip 正式版主要特征:
更新了算法来加大 7z 格式 的压缩比
7-Zip 是基于 GNU LGPL 之下发布的软件

支持格式:
压缩及解压缩:7z、ZIP、GZIP、BZIP2 和 TAR
仅解压缩:RAR、CAB、ISO、ARJ、LZH、CHM、Z、CPIO、RPM、DEB 和 NSIS
对于 ZIP 及 GZIP 格式,7-Zip 能提供比使用 PKZip 及 WinZip 高 2-10% 的压缩比
7z 格式支持创建自释放(SFX)压缩档案
集成 Windows 外壳扩展
强大的的文件管理
强大的命令行版本
支持 FAR Manager 插件
支持 63 种语言

What's new: - 7-Zip now can unpack UEFI BIOS files. - 64-bit version of 7-Zip now includes additional 32-bit shell extension DLL. So other 32-bit programs can call 64-bit 7-Zip via context menu. - Now it's possible to associate 7-Zip with file types without Administrator rights. - New -mf=FilterID switch to specify compression filter. Examples: 7z a -mf=bcj2 a.7z a.tar 7z a -mf=delta:4 a.7z a.wav 7z a -mf=bcj a.tar.xz a.tar - There are some changes in LZMA settings for BCJ2 filter. So compression ratio now is slightly improved for executable files in -mx9 mode for .7z format. - Some bugs were fixed. - New localizations: Corsican, Kyrgyz, Ligurian. What's new in latest alpha update: - 7-Zip now remembers "Show Password" option selection. - The bug in latest alpha versions was fixed: Default solid block size was small (command line version only).

Compression ratio results are very dependent upon the data used for the tests. Usually, 7-Zip compresses to 7z format 30-70% better than to zip format. And 7-Zipcompresses to zip format 2-10% better than most of other zip compatible programs.
