Hi wcwroger,
Just adding it to your drive wouldn't help. One needs to use Google Chrome and it's extension "Copy Folder" to create a copy in own gdrive. One would need a paid version of the drive to make a copy as the size is too big. Chrome extension can be found at https://chrome.google.com/webstore/detail/copy-folder/kfbicpdhiofpicipfggljdhjokjblnhl?hl=en
