TDirectory.GetAttributes、TDirectory.SetAttributes获取和设置文件夹属性

使用函数：

　　System.IOUtils.TDirectory.GetAttributes//获取属性
　　System.IOUtils.TDirectory.SetAttributes//设置属性

注：次例未添加异常处理。

补充一句代码：

CheckListBox1.CheckAll(vcl.StdCtrls.TCheckBoxState(0), False, False);//ListCheckBox取消所有选中

示例：

代码：

unit Unit1;

interface

uses
    Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants,
    System.Classes, Vcl.Graphics,
    Vcl.Controls, Vcl.Forms, Vcl.Dialogs, System.TypInfo, Vcl.StdCtrls,
    Vcl.CheckLst, Vcl.FileCtrl, System.IOUtils;

type
    TForm1 = class(TForm)
        Button_ChooseFolder: TButton;
        Button_GetAttrs: TButton;
        Button_SetAttrs: TButton;
        CheckListBox1: TCheckListBox;
        Label1: TLabel;
        Edit_Path: TEdit;
        procedure Button_ChooseFolderClick(Sender: TObject);
        procedure FormCreate(Sender: TObject);
        procedure Button_GetAttrsClick(Sender: TObject);
    procedure Button_SetAttrsClick(Sender: TObject);
