如何使用innoSetup安装程序和卸载程序删除某些文件

Question

我正在使用innoSetup创建安装程序。下面是我的代码。在我的代码中，我将配置文件保存在“ {userappdata} \ testApp \ settingFiles”中。

; Script generated by the Inno Setup Script Wizard.
; SEE THE DOCUMENTATION FOR DETAILS ON CREATING INNO SETUP SCRIPT FILES!

#define MyAppName "testApp"
#define MyAppVersion "1.00"
#define MyAppPublisher "taichi"
#define MyAppURL ""
#define MyAppExeName "testApp.exe"

设置用户后，我不想删除“ {userappdata} \ testApp \ settingFiles”。

运行卸载程序时，我不想删除此文件夹。

此外，运行安装程序时，我不想覆盖此文件夹。

我该怎么做？
