I had the same thing happen and since I took a snap shot beforehand I deleted the big files. I did have one other thing go wrong though, I was able to login but I got an error when I clicked the Setup button at the bottom of the portal administration page. I don’t think deleting the files had anything to do with error though. Just for fun I tried to update again to 3.3 and after an hour of backing up the database I reverted back to the original snapshot.
