Hi @ScottF ,

From my side and regarding the issue with ‘overwrite Path Variable’ , as mentioned in the topic:
“All these workarounds could be avoided with the implementation of an ‘Overwrite Variable’ function within the ‘String to Path (Variable)’ node.”

An alternative option could be to release a node update with an ‘Overwrite Variable’ option, as it is included in ‘Java Edit Variable (simple)’ node, see picture . It would avoid some workarounds.
