TDirectory.CreateDirectory();     {建立新目录}
TDirectory.Exists();              {判断文件夹是否存在}
TDirectory.IsEmpty();             {判断文件夹是否为空}
TDirectory.Copy();                {复制文件夹}
TDirectory.Move();                {移动文件夹}
TDirectory.Delete();              {删除文件夹, 第二个参数为 True 可删除非空文件夹}
TDirectory.GetDirectoryRoot();    {获取目录的根盘符, 如: C:\}
TDirectory.GetCurrentDirectory;   {获取当前目录}
TDirectory.SetCurrentDirectory(); {设置当前目录}
TDirectory.GetLogicalDrives;      {获取驱动器列表; 下有举例}
TDirectory.GetAttributes();       {获取文件夹属性, 譬如只读、存档等; 下有举例}
TDirectory.SetAttributes();       {设置文件夹属性; 下有举例}

{获取、设置文件建立时间、修改时间、读取时间}
TDirectory.GetCreationTime();
TDirectory.SetCreationTime();
TDirectory.GetLastWriteTime();
TDirectory.SetLastWriteTime();
TDirectory.GetLastAccessTime();
TDirectory.SetLastAccessTime();

{使用 Utc 时间格式读取或设置}
TDirectory.GetCreationTimeUtc();
TDirectory.SetCreationTimeUtc();
TDirectory.GetLastWriteTimeUtc();
TDirectory.SetLastWriteTimeUtc();
TDirectory.GetLastAccessTimeUtc();
TDirectory.SetLastAccessTimeUtc();


测试代码:
unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm1 = class(TForm)
    Memo1: TMemo;
    Button1: TButton;
    Button2: TButton;
    Button3: TButton;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
    procedure Button3Click(Sender: TObject);
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

uses IOUtils, Types, TypInfo;

//TDirectory.GetLogicalDrives; {获取驱动器列表}
procedure TForm1.Button1Click(Sender: TObject);
var
  s: string;
  arr: TStringDynArray;
begin
  arr := TDirectory.GetLogicalDrives;
  Memo1.Clear;
  for s in arr do Memo1.Lines.Add(s);
end;

//TDirectory.GetAttributes(); {获取文件夹属性, 譬如只读、存档等}
procedure TForm1.Button2Click(Sender: TObject);
var
  fas: TFileAttributes;
  fa: TFileAttribute;
begin
  fas := TDirectory.GetAttributes('c:\Windows');
  Memo1.Clear;
  for fa := Low(TFileAttribute) to High(TFileAttribute) do
    if fa in fas then Memo1.Lines.Add(GetEnumName(TypeInfo(TFileAttribute), Ord(fa)));
end;

//TDirectory.SetAttributes(); {设置文件夹属性, 这里是设置为隐藏}
procedure TForm1.Button3Click(Sender: TObject);
const
  path = 'c:\temp\ABC';
begin
  TDirectory.CreateDirectory(path);
  TDirectory.SetAttributes(path, [TFileAttribute.faHidden]);
end;

end.
