if you want to use C:\nxp\eIQ_Toolkit_v1.0.5\workspace\importer\Structured Folders Importer.ipynb directly you need to prepare your dataset, as described in DeepViewRT for RT1170 - Data Import Lab.pdf (5.1 Setup the image directory structure).
You can change created *.eiqp project name as you want, please see example below:
project = ds.create_project('C:\\Users\\User.Name\\Desktop\\eiq_test\\flower_new_project.eiqp')
It creates project named flower_new_project.eiqp in eiq_test folder (this folder it has to exist).
If you have dataset structure such as subfolders which names corresponds to labels and each subfolder contains whole bunch of images corresponding to particular label, please refer to this link
