7-Zip软件特性

7-Zip解压软件是一个开放源码的数据压缩程序，7-Zip主要用在Microsoft Windows操作系统，Unix-like的操作系统，本站提供7-Zip解压软件官方版下载。
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 9.20.11:
What&39;s new: - 7-Zip now can unpack UEFI BIOS files. - 64-bit version of 7-Zip now includes additional 32-bit shell extension DLL.

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.
