Question

我想找到一种只卸载已安装文件的方法。我尝试了http://nsis.sourceforge.net/Uninstall_only_installed_files但是我有大约10.000个文件嵌套在许多目录中，因此在nsis脚本中单独指定每个文件不是解决方案。

您可以使用!system命令在编译时执行外部工具。此外部工具/脚本应生成包含安装和卸载说明的包含文件。

您也可以动态使用NSIS来生成说明，但是当您将所有内容放在一个脚本中时它会有点乱：

; Generate some files for this example:
!system 'mkdir "$%temp%\testdir\subdir\sub2\sub3"'
!appendfile "$%temp%\testdir\file1.txt" ""
!appendfile "$%temp%\testdir\subdir\file2.txt" ""
!appendfile "$%temp%\testdir\subdir\sub2\file3.txt" ""
!appendfile "$%temp%\testdir\subdir\sub2\sub3\file4.txt" ""



!macro GENFILELIST_Enum SourceDir InstDir
Push "${SourceDir}"
Push "${InstDir}"
Call GENFILELIST_Enum
!macroend

SetOutPath $InstDir
!include "${FileInstructions}"
SetOutPath $Temp
Delete "$InstDir\Uninst.exe"
RmDir $InstDir
SectionEnd
!macroend
