How to utlize this dataset?

I wonder how can I utilize the extended dataset for PartNet segmention in this https://github.com/FENGGENYU/CVPR2019_PartNet.git. Because I observed that the folder structure in the data provided is different with the extended dataset, I wonder if there is a way to reorganize the folder structure of the extended dataset so that I can run the PartNet for the extended dataset? Thank you very much!
