I have been using it at work for many years. It's very helpful, but sometimes the upload or download doesn't proceed.
At that time, the message "Synchronizing XX files" will be displayed and no progress will be made for several days. If I could figure out which file is taking the time, I could temporarily save it, but I can't do anything about it because I don't know which file is the problem. Is it possible to have the Dropboxdesktop app display which files are being synced?
