Hola Mariana, si el codigo anterior no te funciona pruebe este.

procedure TForm1.Button1Click(Sender: TObject);
var
DirInfo: TSearchRec;
r : Integer;
begin
r := FindFirst('C:\Download\Test\*.*', FaAnyfile, DirInfo);
while r = 0 do begin
if ((DirInfo.Attr and FaDirectory <> FaDirectory) and
(DirInfo.Attr and FaVolumeId <> FaVolumeID)) then
if DeleteFile(pChar('C:\Download\test\' + DirInfo.Name))
= false then
{Si no puede borrar el fichero}
ShowMessage('Unable to delete : C:\Download\test\' +
DirInfo.Name);
r := FindNext(DirInfo);
end;
SysUtils.FindClose(DirInfo);
if RemoveDirectory('C:\Download\Test') = false then
{Si no puedes borrar el directorio}
ShowMessage('Unable to delete dirctory : C:\Download\test');
end;

Espero te sirva.
