Copy File In Stored Procedure

All I want to do is copy a text file and add a 1 after the name in a stored procedure that already cretes this file.



CREATE PROCEDURE [dbo].[sp_export_req] AS
DECLARE @trenutniRed varchar(30),
@tableRow1 varchar(3000),
@sql varchar(4000),
@sql1 varchar(4000),
@firstColumnName varchar(30),
@HTMLfile varchar(1000),
@columnNumber varchar(30),
@fs int,
@ole int,
@file int
declare @body as nvarchar(225)
CREATE TABLE #temptableHTML (code nvarchar(225))
select @HTMLfile = 'c: est_new.txt'

This is the start of the procedure that creates the test_new.txt file. I want to copy the test_new.txt file and name it test_new1.txt. Any help is appreciated. thank you
