This node allows to create path flow variables. This is done by selecting a base folder and then defining a list of paths pointing to files/folders relative to the base folder. After executing the node the specified list of paths is accessible for subsequent nodes via flow variables.
Note: The default base folder is the working directory of the workflow data area, as defined by “.“ in the Folder field.
This node can access a variety of different file systems. More information about file handling in KNIME can be found in the official File Handling Guide.
