We've just set up a new account with unlimited storage and a 15GB filesize upload limit. When copying files from a client's shared folder, all of the small files will copy fine, but anything over 1GB produces the error "You don not have enough space to copy the item "<item name>" and fails.
I am able to download every file I've tried via browser and Box Drive (on a Mac, FWIW). I can also upload these larger files if I move them to my desktop first then copy them to the target directory, but not if I try copying them with Box Drive directly from the original shared folder to the folder owned by us.
Why don't we have unlimited space in our account?
