MSI文件使用的压缩方法是什么? [英] What is the compression method used by MSI files?

问题描述

我可以提取MSI文件，但是当我尝试从提取的文件中重新生成MSI文件时，结果文件不起作用.

I can extract a MSI file, but when I try to regenerate it from the extracted files the resulting file doesn't work.

我猜想，如果我将压缩方法从Deflate更改为另一种压缩方法，那么它将起作用.

I guess that if I changed the compression method from Deflate to another one, it would work.

推荐答案

首先:Windows Installer SDK中有一个名为 WiMakCab.vbs 的脚本，用于创建* .cab文件.用于MSI文件.该脚本中的行之一是:Dim compressType : compressType = "MSZIP").创建出租车时，您可能应该尝试使用该脚本.

First of all: there is a script in the Windows Installer SDK called WiMakCab.vbs which is used to create *.cab files for use in MSI files. One of the lines in that script is: Dim compressType : compressType = "MSZIP"). You should probably try that script when creating the cabs.

Below is an annotated quote from http://www.gdgsoft.com/ (16.06.2014: removed direct broken link, leaving the base url):

" Microsoft Cabinet 支持三种无损压缩技术:(1)存储，(2) MSZip 和(3) LZX .在机柜归档文件中，可以使用这些技术的任意组合.MSZip本质上与PKZip使用的放气压缩方法相同.LZX是LZ77-基于压缩的技术，它使用静态霍夫曼编码.LZX使用更多的内存，但是比MSZip可以产生更好的压缩率.当然，存储意味着文件未压缩就存储在文件柜中."

"Microsoft Cabinet supports three lossless compression techniques: (1) storing , (2) MSZip, and (3) LZX. Within a cabinet archive file, any combination of these techniques may be used. MSZip is essentially the same as the deflation compression method used by PKZip. LZX is an LZ77-based compression technique that uses static Huffman encoding. LZX uses more memory, but can produce better compression ratios than MSZip. Stored, of course, means the file is stored into the cabinet uncompressed."
