I have a Dropbox Plus plan and am running Windows 10. My PC is out of space and I need to get a lot of the Dropbox files off my PC. I've read Help articles & posts in the community, and nothing is working.
I have downloaded and run the Dropbox installer 5 times, and there is still no icon in my system tray. When I click the Dropbox icon in my menu bar, it just opens my Dropbox folder.

On Dropbox.com, when I go to my account and click "General", then look at "Preferences", there is nothing about syncing preferences.

I have exchanged several emails with Dropbox support, but they say that I must go through my computer and delete all the files that are located both in Dropbox and also locally on my computer. I think they are misunderstanding the problem. I need to use smart sync to get the Dropbox files off my computer. I do not need to also get the duplicate files off my computer. The Dropbox files ARE my duplicates.
I'd appreciate some guidance. Thanks!
