Transfer File Node - Downloading multiple pdf files from the web and storing all in a local directory

KNIME Analytics Platform
1

Hi Friends,

I’m able to use the Transfer File node in KNIME to download a single PDF file from the internet and store it in a local directory by setting the “Read from custom/KNIME URL” option manually.

Now, I need to download multiple PDF files in one go. My assumption is that I can pass the file URLs dynamically using a flow variable. To achieve this, I used a Table Row to Variable Loop Start, but the Transfer File node does not seem to recognize the flow variable in the “Read from custom/KNIME URL” field – the “Use variable” option remains disabled or doesn’t detect the variable.

Has anyone successfully used a loop to batch download files using this node? Am I missing a configuration step, or is there a workaround for this?

Thanks in advance!
