演示如图：

代码如下：

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    Button1: TButton;
    Button2: TButton;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
var
  f:file;
begin
AssignFile(F,'game.exe'); // 将game.exe文件与F变量建立连接，后面使用F变量对文件进行操作。
ReName(F, 'game.bin'); // 将game.exe变为game.bin
end;

procedure TForm1.Button2Click(Sender: TObject);
var
  f:file;
begin
AssignFile(F,'game.bin'); // 将game.exe文件与F变量建立连接，后面使用F变量对文件进行操作。
ReName(F, 'game.exe'); // 将game.bin变为game.exe
end;

end.
