高效解压软件 - 7-Zip 最新正式版官方版及便携版

7-Zip是一款免费开源的号称有着现今最高压缩比的文件压缩管理软件,它不仅支持独有的7z文件格式,而且还支持各种其它压缩文件格式,其中包括ZIP, RAR, CAB, GZIP, BZIP2和TAR等等。此软件压缩的压缩比要比普通ZIP文件高30-50%,因此,它可以把Zip格式的文件再压缩2-10%。


17.01 beta 2017-08-28

- Minor speed optimization for LZMA2 (xz and 7z) multi-threading compression.

7-Zip now uses additional memory buffers for multi-block LZMA2 compression.

CPU utilization was slightly improved.

- 7-zip now creates multi-block xz archives by default. Block size can be

specified with -ms[Size]{m|g} switch.

- xz decoder now can unpack random block from multi-block xz archives.

7-Zip File Manager now can open nested multi-block xz archives

(for example, image.iso.xz) without full unpacking of xz archive.

- 7-Zip now can create zip archives from stdin to stdout.

- 7-Zip command line: @listfile now doesn’t work after — switch.

Use -i@listfile before — switch instead.

- The BUGs were fixed:

7-Zip could add unrequired alternate file streams to WIM archives,

for commands that contain filename wildcards and -sns switch.

7-Zip 17.00 beta crashed for commands that write anti-item to 7z archive.

7-Zip 17.00 beta ignored “Use large memory pages” option.
