Clear everything from node-red

Thanks Colin.
ok but how to delete the feed file?
if I want to delete Alarme_v01, so all the elements on the "Alarme_v01" page image below how do we do it?

to see the hidden streams, I did: search you flows + flow

I ask how to delete the example files that I downloaded from the internet to learn, but then I don't know how to delete them and keep only the pages that I modified

I'm a beginner and for me it's a bit complicated.
thank you for your patience
