7-Zip是一款GNU/LPGL协议下分发的开源软件,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.
What's new after 7-Zip 4.57:
- Some speed optimizations.
- 7-Zip now can unpack .lzma archives.
- Unicode (UTF-8) support for filenames in .ZIP archives. Now there are 3 modes:
1) Default mode: 7-Zip uses UTF-8, if the local code page doesn't contain required symbols.
2) -mcu switch: 7-Zip uses UTF-8, if there are non-ASCII symbols.
3) -mcl switch: 7-Zip uses local code page.
- Now it's possible to store file creation time in 7z and ZIP archives (-mtc switch).
- 7-Zip now can unpack multivolume RAR archives created with
"old style volume names" scheme and names *.001, *.002, ...
- Now it's possible to use -mSW- and -mSW+ switches instead of -mSW=off and -mSW=on
- Some bugs were fixed.
- New localizations: Punjabi (Indian), Pashto.
