I've moved Dropbox location from system drive to other drive (from Preferences -> Sync -> Change location). It completed moving after 5 hours.
It's been few days since the move and the app is stuck now at "Downloading 31 files...". In Explorer, most of the files have this icon:

I have enough disk space on my PC, enough space left on Dropbox account, decent connection and brand new PC.
The files it tries to download have extension ".js.download", likely from incomplete website backup.
Before the move, the app was not stuck. Why is it even trying to "download" something when I only moved the folder? How do I unclog the app?
