OneDrive recently increased its maximum supported file size from 2 GB to 10 GB,[+]. To echo other comments in this thread, it's likely that "Unlimited" storage is a rebranding and publicity move because most paid users were not using anywhere near the 1+ TB they had access to anyways. To me, it seems likely that the file size limit could be lifted for similar purposes soon.

They should remove/increase the file size and count limit first. Technically, that's also probably the bigger challenge.

Again, I know, pain in the ass, but it's a work around.
Then you'll run into the 20,000 item limit faster...
