Cold Backup Script for windows

Question

Hi,
I have the following script for windows
set pages 0 lines 500;
set heading off echo off feedback off verify off pagesize 0;
select 'copy ' || name || ' c:\BACKUP\COLD_BACKUP\ORADATA\' from v$datafile
union all
select 'copy ' || name || ' c:\BACKUP\COLD_BACKUP' from v$controlfile
union all
select 'copy ' || member ||' c:\BACKUP\COLD_BACKUP' from v$logfile
union all
select 'copy ' || name || ' c:\BACKUP\COLD_BACKUP' from v$tempfile;
exit;
In the above script I have given COLD_BACKUP directory for Backup....But what i want is Dynamically it should create the Directory with timestamp in COLD_BACKUP Directory and copy the files to that directory..
for example
script should create like this
c:\BACKUP\COLD_BACKUP\ORCL_11112007
Like that..it should create the ORCL_11112007 directory and copy the files....
how can i acheive this...I know we can do it in UNIX..
But in windows..how we can acheive this...please help me

You can try to adapt the following SQL*Plus script to create a directory:
set echo on
alter session set nls_date_format = 'DDMMYYYY';
var dd varchar2(10);
begin
:dd := trunc(sysdate);
end;
set echo off
spool mkd.sql
set heading off
select 'host mkdir ' || :dd from dual;
spool off
set echo on
@mkd.sqlOutput is:
dev001> alter session set nls_date_format = 'DDMMYYYY';
Session altered.
dev001> var dd varchar2(10);
dev001>
dev001> begin
  2  :dd := trunc(sysdate);
  3  end;
  4  /
PL/SQL procedure successfully completed.

dev001> set echo off
host mkdir 08112007
dev001> @mkd.sql
dev001>
dev001> host mkdir 08112007
dev001>
