Excellent - thanks gents. Must admit its been a very long time since I last used SFTP! Forgot all about that - it will be like a lovely stroll down memory lane!
I forgot to mention I use Mac/OSX… but just confirmed CyberDuck has similar functionality Bill - so thanks for prompting that thought also.
Mike - I use ExpanDrive for Mac to mount an emonPi as a drive on my Mac. It transfers files nice and fast these days (older versions were somewhat slow). It goes on-sale once in a blue moon for about 50% off.
