I've been a Dropbox user for a few years and gradually it's become clunky, unuseable and bloated. I like to keep it simple as online storage for files and very occasionally I will sync a folder. Can you do it? Actually you can't. No matter what settings it will always sync to your local Dropbox folder on your hard drive taking up massive amounts of space. Then they introduced Smart Sync (I keep telling them I don't want to sync at all) which even though it has an option for online only, it STILL puts a copy on my hard drive. It took tech support weeks to respond saying there were still issues. I had give up. I'm now with Google One which is better and cheaper. Dropbox; too bloated, too clunky, too complicated.
