the current date DD/MM/yyyy as the text file name

exec ('exec master..xp_cmdshell ''E:\Inetpub\wwwroot\BIASS\wzzip.exe E:\Inetpub\wwwroot\'+@.SiteFolder+'\Admin\BIA_DataF eed\'+@.FileName+'.zip E:\Inetpub\wwwroot\'+@.SiteFolder+'\Admin\BIA_DataF eed\'+@.FileName+'.'+@.defaultCSVFeed_FileType+''' ')
