My folders have been synced but I don't see any files [closed]
Depending on what version of Ubuntu you're on, what you're seeing is normal. Folders get created first, and then files. Very slowly, if we're talking thousands of files.
We've worked on fixing this slowness and it should be much better by the time we release Natty, on Natty; older versions will get the speedups soon after that.
Meanwhile, to make sure you are progressing, you can follow the instructions on How can I tell whether Ubuntu One file sync is working, and what progress it is making?
