Upload own files from my own pc with Node Red Dashboard

Yes its correct.

Replies of your questions:

  1. Yes. Both PCs are running the NodeRed dashboard in a browser.
  2. It can be a normal dashboard with normal packages like graphs.
  3. The NodeRed server is running on both PCs like we start it in terminal or cmd and the dashboard in the browser.

Its difficult to explain it for me because my English it not so good. I am very sorry about that. But I told you I want to take a file from my PC upload it with NodeRed and the other PC want it tu download it.
