RMAN creates . files in 12c

Oracle 12c RMAN backup would create . (hidden files) if you are using NAS storage for the backups. These . files would be converted to regular files once rman stops writing to the backup piece.  This is because DNFS is enabled by default in 12c and this is cauing this behavior. Solution is to disable dnfs and you will start seeing normal files even when rman is writing to the backup pieces.
