仅卸载已安装的文件 NSIS

Question

我想找到一种只卸载已安装文件的方法。我试过 http://nsis.sourceforge.net/Uninstall_only_installed_files 但我有大约 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 tool/script 应生成包含安装和卸载说明的包含文件。

您也可以即时使用 NSIS 生成指令，但是当您将所有指令放在一个脚本中时会有点混乱：

; 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
