Thanks for the reply,
I am wanting to use the batch file route, just out of preference.
I already have sync software supplied with the external drive. I'd rather stay in control of what is being copied, etc. A piece of software might delete something and before I know it, its too late!
I want to know if there is a 'switch' or command in a batch file that deletes the backed up directory if it no longer exists in the source, to save me from deleting it from both or deleting my backup to recopy it.
