卸載僅安裝的文件NSIS

Question

我想找到一種方法來卸載只安裝的文件。 我試過http://nsis.sourceforge.net/Uninstall_only_installed_files，但我有大約10.000個文件嵌套在許多目錄中，因此在nsis腳本中單獨指定每個文件並不是一個解決方案。

您可以使用!system命令在編譯時執行外部工具。該外部工具/腳本應該生成包含安裝和卸載說明的包含文件。

您還可以使用NSIS的飛行產生的指令，但是當你把所有的它在一個腳本這是一個有點亂：

; 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
