I have many jpg files and some txt file in 100 sub-folders. How to select one jpg file at a time and loop through all the sub-folder for all jpg files but not other file type?

You need this : [node-red-contrib-fs (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-fs)

But how to make Node-Red go over the files one by one with the file name too many to write? Do I need to write codes in function node to read through them or there is a node can do it?
