Write file to a local disk drive

General
1

I am injecting a simple 'Hello' string into a file and want to save the file to my local PC. However, since Node-RED is running on a server, all attempts have resulted in the file being written to the server instead. Is it possible to write the file directly to my local machine?

One way (and the way I often use) is to use SCP (secure copy protocol) inside an Exec node.

I suggest you do a little research on SCP first (eg What is SCP Protocol? A Complete Guide) to see if it suits your needs.

That is the process of Downloading a file from the server to the PC running the browser. I have not done this myself, but If you search the forum for Download File I expect it will produce a number of possibilities.

The node @prescient-devices/node-red-contrib-downloadfile can accomplish what you desire. You can find it here.
