Google drive is a pain.. I don't know how you managed to download everything. I downloaded each sub folder under contents then sub folders in data individually. Each time had to be zipped.
What was the total file size you have? I ended up with 3.48 GB, 5,492 files, 54 folders.
The old one totals at 6.05 GB compressed. I will wait another day to try the old files, need a break from google drive..
