I have a folder that won't disappear no matter how many times I delete it. It pops back in for me, and for other users. This has happened before when someone on a Mac put a funny character in the filename, so the file wouldn't sync on my PC. However, that's not the case here. There are two empty folders in another folder, and I cannot delete any of them, or move them. How do I make it go away? I've cleared my registry, restarted the computer, deleted it from both the online account and the desktop app. Nothing works.
