relationship between the downloaded Motion-X and Motion-X++ data

[KunhangL]

Hi~ Thanks for your time and efforts devoted to the dataset release! I have downloaded both Motion-X and Motion-X++ data through the Google drive link, but I'm wondering about the relationship between the two folders. Should I merge the two datasets to the same folder or keep them separate? It seems that in both datasets there are motions from the same sources (e.g., there is idea400 in both Motion-X and Motion-X++)
