reading multiple files

Hello,

I am new to KNIME and I must say it is extremely useful.

I would appreciate any help for a problem I am facing. I have multiple SD files I would like to read in. Instead of using multiple "SDF Reader" nodes, I thought of using "List Files" and then "Iterate list of file" nodes. When I run the "List Files" node, I get a table with location and file names. However, for the "Iterate list of files" node, I get the warning message that there are no settings available. I have no idea what is wrong!

Thanks in advance,

Preeti
