Was not sure on this as the notes on v1.4.1 (my first hit) say:
Simple node to copy files
But I notice on GitHub that the move ability is listed and another link shows this is possible in a later version node-red-contrib-fs-ops (node) - Node-RED
Bit concerned the two versions show up with no link between them or a way of selecting the latest on the page - going to raise question on this...
Wonder how much else I've missed...
