there's already a folder or file named dropbox
I've had Dropbox installed for several years on a Mac but had not used it for a few years. When I tried launching it, nothing happened, so I downloaded a new copy and installed it. With the installation came a pop-up message "there's already a folder or file named dropbox," at which point I either had to rename the existing Dropbox folder or choose another new one. That would mean copying several GB of files (needlessly) from a cloud server to an empty folder, with the previous folder no longer synced. I have a very slow cellular-phone based service (all that's available where I live - no fiber optics coming to our neighborhood), and it's metered. This 'feature' essentially makes Dropbox unusable for local storage. There have been other postings of this problem over at least 5 years, with no solution from Dropbox. A proposed solution is to rename the old Dropbox, let the process start syncing to a new one, stop the process, move the old to the new, and restart Dropbox. As far as I can tell, this just delayed the inevitable process of copying several GB of files. I cannot afford this. Yes, I can always access files on the web, but that makes Dropbox more primitive than most other cloud servers that have native Mac, Windows, and even Linux clients.
