Dropbox tells me to right click on folder and choose Smart Sync but I don't have this option

I have some 5-year old videos in my Dropbox folders. Apparently they were only partly downloaded using SmartSync, because instead of getting a thumbnail I get a crossed icon:

When I try to play one of them in VLC I can't:

Opening in any other software or uploading them to youtube doesn't work either. These files are broken.

There seems to be no fix for this other than manually downloading the broken files from dropbox.com.

I can't seem to even disable SmartSync, I remember this option used to be there in Preferences but it's gone now:

Please tell me how to disable this horrendous SmartSync forever!
It's causing only problems and brings no benefits, I have enough space on my HD to download all files anyway, and if I happen to run out of space I'd rather prefer to use Selective Sync instead.

That icon isnt anything to do with Dropbox ned666 its a windows one: https://support.microsoft.com/en-us/office/what-do-the-onedrive-icons-mean-11143026-8000-44f8-aaa9-67c985aa49b3?ui=en-us&rs=en-us&ad=us#ID0EBH=Windows

You'll not see the SmartSync menus etc. if you are not on a paid plan as they are account type specific: https://help.dropbox.com/installs-integrations/sync-uploads/smart-sync

I've merged both posts together or things get complicated

Based on your first post Dropbox isnt running, or, doesnt have overlays etc. set up

Try a reinstall: www.dropbox.com/downloading

I am on a paid plan (2 TB).

This is really strange, I don't have this issue on my second PC. I'm logged in as same account, Dropbox version is the same (v149.4.4568) and yet I see only half of the options in Preferences > Sync tab that I see on the other PC.

Hi, yes, reinstalling helped regarding SmartSync, but now I'm struggling with other problem.

1. Dropbox is stuck at "Dowloading 3 files" since Monday
2. I cannot figure out which 3 files, because the syncing icon overlays are not visible anymore in Windows Explorer
Will try to figure it out myself first, if it doesn't help I will open a new thread.

Thanks for all the updates, ned666!

As for the syncing of the app, I'd suggest a restart, or even for you to sign out of the app and then back in. 

Let me know how it goes in any case. 

Hi , not sure if anyone can help me or how to contact anyone. Sadly I use Dropbox. I actually hate it however all my files and folders dating back years are in it. I didn't know that files were still on my Mac and now have run out of disk space. I have read some of the online advice and it says I need to make some files online only. This is fine however to do this I need to access preferences and do some hovering? I have no dropbox icon in the tool bar ( also cannot for the life of me figure out how to get this back) . Then I understand I can make some files online only? How can I do this if I cant access the preferences??? Makes no sense at all to me at all. I can only access dropbox via finder and obvs dont have a right click( ?) as its a Mac? Is there anyway I can speak to someone or get any advice on this before I throw my laptop out of the window? 

ihatedreaming if you have no icon on the status bar Dropbox isnt running.

Simply start it from within the Applications folder and you will find it and also get the rightclick menus 

WOW thanks Ill try what you suggest...
