压缩文件与PPMD压缩，以编程方式解压缩 [英] Zip File with PPMD Compression, Programmatically Unzip

问题描述

我有一个Linux Python脚本，需要解压缩一些zip文件。我正在使用zipfile模块。在这些文件中的一些我得到：

  BadZipfile：不支持的压缩方法98文件
  

搜索这些文件似乎是使用方法98 PPMD​​压缩。我想如果python不能做到这一点，我会做一个黑客系统调用解压缩6.0并完成它。此错误：

  skipping：fileName`PPMd'方法不支持
  

我试过7zip：

 提取fileName不支持的方法
  

我以为我用命令行实用程序ppmd命中了pay-dirt，但是：

 用于文本数据的快速PPMII压缩器，变体I，2009年11月6日

还有什么我可以试试吗？ WinZip在Windows中没有这些文件的问题，但我需要在Linux中这样做。
解决方案
 p7zip（二进制）？ 
 
 
 
似乎支持PPMD压缩格式。
 
 
 
一些PPMd开关：-mmem = 24b，-mmem = 24k，-mmem = 24m，-mo = 2和-mo = 32 
 
I have a Linux Python script that needs to unzip some zip files.  I was using the zipfile module.  On a few of these files I'm getting:
BadZipfile: Unsupported compression method 98 for file
Searching around it seems these files are using Method 98 PPMD compression.  I figured if python couldn't do it, I'd make a hack system call to unzip 6.0 and be done with it.  This errors:
skipping: fileName `PPMd' method not supported
I've tried 7zip:
Extracting  fileName     Unsupported Method
I thought I hit pay-dirt with a command line utility ppmd, but:
Fast PPMII compressor for textual data, variant I, Nov  6 2009
Segmentation fault
Anything else I can try?  WinZip in windows has no problem with these files, but I need to do this in Linux.
解决方案
Have you taken a look at the p7zip (binary)? 

It seems to support the PPMD compression format.

Some PPMd switches:  -mmem=24b, -mmem=24k, -mmem=24m, -mo=2, and -mo=32
