Reader Nodes: Using relative paths to import data

Hello @Henan You will have to create your folder structure within the ‘Current workflow data area’… this is by adding a ‘data’ folder into your workflow folder structure. i.e. You have a workflow saved as ‘KNIME_test’ (see picture). You can manually add an empty ‘data’ folder from your file explorer, and reproduce your folder structure within it. Then you can use ‘Browse button’ with ‘Relative to’ - ‘Current workflow data area’ node configuration. [image] BR
