急求操作 C:/Documents and Settings/[用户名]/Local Settings/Temporary Internet Files 文件夹

急求操作 C:/Documents and Settings/[用户名]/Local Settings/Temporary Internet Files 文件夹的方法(50分)<br />急求操作 C:/Documents and Settings/[用户名]/Local Settings/Temporary Internet Files 文件夹的方法，各位大虾看清楚了，不是别的文件夹，操作普通文件夹的方法对这个没效果。 希望能给个例子，删除这个文件夹里面的文件

如果是在執行中的文件就删除不了啊

不删除也行，，，就取这个文件夹里面的所有文件的文件名

//删除COOKIES

unit Unit1;

interface

uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls, Registry, ShlObj, ShellApi, WinInet, ExtCtrls;

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

var
Form1: TForm1;

implementation

{$R *.dfm}

procedure DelRegCache;
var

begin
reg:=Tregistry.create;
reg.RootKey:=HKEY_CURRENT_USER;

reg.Free;
end;

function GetCookiesFolder:string;
var
pidlItemIDList;
buffer:array [ 0..255 ] of char ;
begin
SHGetSpecialFolderLocation(
application.Handle , CSIDL_COOKIES, pidl);

SHGetPathFromIDList(pidl, buffer);
result:=strpas(buffer);
end;

function ShellDeleteFile(sFileName: string): Boolean;

begin
wFunc := FO_DELETE;//删除
pFrom := PChar(sFileName);

end;
Result := (SHFileOperation(FOS) = 0);
end;

procedure DelCookie;
var
dir:string;
begin
InternetSetOption(nil, INTERNET_OPTION_END_BROWSER_SESSION, nil, 0);
dir:=GetCookiesFolder;
ShellDeleteFile(dir+'/*.txt');
end;

procedure DelHistory;
var

if dwLastError = ERROR_INSUFFICIENT_BUFFER then //如果成功

end.

上面代码调试过了，是我想要的效果[]不过怎么这么长啊，我以为这个功能代码应该比较短的，得慢慢研究了[] 散分

japhe, 当cookies无法删除文件的时候上面一段代码会报错，异常夜解决不了，该怎么解决啊

这个我也碰到过，在WIN2K中没问题，在XP系统中好象是会出错的，呵呵。
