CreateProcess problem med copy statement

Hvorfor virker copy linien ikke når notepad linien gør:

program Project2;

{$APPTYPE CONSOLE}

uses
  Windows,
  SysUtils;

procedure CreateProcessSimple(FileNameAndParameters:string; Wait:Boolean);
var
  pi: TProcessInformation;
  si: TStartupInfo;
begin
  FillMemory( @Si, SizeOf( si ), 0 );
  si.cb := SizeOf( si );

  CreateProcess(Nil, PChar(FileNameAndParameters), Nil, Nil, False, NORMAL_PRIORITY_CLASS, Nil, Nil, si, pi );

  if Wait then
    WaitForSingleObject(pi.hProcess,INFINITE);

  CloseHandle( pi.hProcess );
  CloseHandle( pi.hThread );
end;

begin
  CreateProcessSimple('copy "C:\BlaBla.txt" "C:\Temp"', True);
  CreateProcessSimple('notepad.exe', True);
end.
