As with all Google links not containing zipped subfolders:
It contains multiple folders.
I strongly suggest you download each volume one after the other.
They will come up in multiple ZIP files that aren’t connected, which means that when you will unzip zip001 it will only unzip this file and not all of the ZIPs.
Once the first file unzipped, consider it as your main folder where you will copy the contents of the other unzipped files.
Then unzip zip002, copy its content in your main folder by merging it and not replacing it.
Repeat this step for the other zip files.
Thank you Yves for allowing access to your Fab library.
