Windows 的内置 ZIP 压缩可以编写脚本吗? [英] Can Windows' built-in ZIP compression be scripted?
问题描述
Windows XP/Vista/2003/2008 中内置的 ZIP 压缩是否可以编写脚本?我必须从 BAT/CMD 文件调用什么可执行文件?还是可以用 VBScript 来实现?
Is the ZIP compression that is built into Windows XP/Vista/2003/2008 able to be scripted at all? What executable would I have to call from a BAT/CMD file? or is it possible to do it with VBScript?
我意识到使用 WinZip、7-Zip 和其他外部应用程序,但我正在寻找不需要安装外部应用程序的东西.
I realize that this is possible using WinZip, 7-Zip and other external applications, but I'm looking for something that requires no external applications to be installed.
推荐答案
zip 和 unzip 也使用 windows 内置压缩,这应该对系统如何运行提供一些见解.您可以将这些方法构建到您选择的脚本语言中.
There are VBA methods to zip and unzip using the windows built in compression as well, which should give some insight as to how the system operates. You may be able to build these methods into a scripting language of your choice.
基本原理是,在windows中,你可以把一个zip文件当作一个目录,复制进去和从里面复制出来.因此,要创建新的 zip 文件,您只需创建一个扩展名为 .zip
的文件,该文件具有空 zip 文件的正确标头.然后你关闭它,并告诉 windows 你想将文件复制到它,就像它是另一个目录一样.
The basic principle is that within windows you can treat a zip file as a directory, and copy into and out of it. So to create a new zip file, you simply make a file with the extension .zip
that has the right header for an empty zip file. Then you close it, and tell windows you want to copy files into it as though it were another directory.
解压更容易 - 只需将其视为一个目录即可.
Unzipping is easier - just treat it as a directory.
万一网页再次丢失,这里有一些相关的代码片段:
In case the web pages are lost again, here are a few of the relevant code snippets:
Sub NewZip(sPath)
'Create empty Zip File
'Changed by keepITcool Dec-12-2005
If Len(Dir(sPath)) > 0 Then Kill sPath
Open sPath For Output As #1
Print #1, Chr$(80) & Chr$(75) & Chr$(5) & Chr$(6) & String(18, 0)
Close #1
End Sub

On Error Resume Next
bIsBookOpen = Not (Application.Workbooks(szBookName) Is Nothing)
End Function
