I have been developing a complex flow over a period of time and have at various stages made exports of the flow. Two questions:-

1. how to I restore to an earlier export of the flow
2. the gold prize, how can I load my latest export of the flow so that I can modify it before it runs an inject node that causes a loop which effectively crashes the system. I did not notice the possibility when testing. It only came to light when the flow was restarted when NR was restarted. Thank you very much if you can help.

You can stop node-red and start node-red in safe mode. [Running Node-RED locally : Node-RED](https://nodered.org/docs/getting-started/local#command-line-usage)

To restore an export you can delete the one you have and import the exported flow.

Safe Mode is the key - thank you so much
