Example workflow is not recognized in KNIME


I am new to KNIME and use version 3.1.3 on Windows. I was following Rosario Silipo's video on how to import the example workflows into KNIME (the ones on the DVD from OReily). When she did that, all the  files within the original KNIMEWorkflow.knar file were opened and added to the Local workspace on the KNIME exploere panel. When I do it, the file is added to the Local workspace just like it was, without opening any of its folders or files, as if it is an unrecognized format.

Could you tell me what is wrong?

I have attached the pictures.

You need at least version 3.2 in order to import .knar files.
