Combine flow variables into CSV file path

KNIME Analytics Platform
#1

I have a workflow that creates several CSV files.

Is it possible to combine the CSV file path from multiple flow variables? I have the directory from a Create Folder node and the CSV file name can be passed from the data table.

I know that I can select a flow variable for the path in the CSV Writer node but I have not figured out how to merge different variables.

Of course. Use node String Manipulation (Variable). Then, depending on KNIME version, you may need String to Path converter added before passing variable into CSV writer.

There is also a merge variable node which you might use

Thanks @Experimenter, that works. It took a few tries but now I managed to use a combination of String Manipulation and String to Path to get output paths into the CSV Writer.
