Oracle Database Discussions

I have been getting this warning in my alert log saying that

cannot delete oracle managed file 'f:\oracle\..\FRA\Autobackup\something.bkp

I moved this particular file to an external disk and so rman is not finding this piece at that particular location.
This is basically an autobackup (controlfile,spfile) ..how can i crosscheck an autobackup and let rman know that this location is expired?


Thanks.
