Create File Name

KNIME Base Nodes version 4.0.1.v201908131444 by KNIME AG, Zurich, Switzerland

This node takes a base directory path, a file name, and a file extension to create a new file path. Inputs can be entered in the configure dialog, or optionally set by flow variables. The output is a flow variable, which can typically be used as input for a writer node (e.g CSV Writer, Table Writer, etc).


Base directory

File name

File extension
