I've unsynced some folders via selective sync, but they're still showing in my local Dropbox folder.

In an attempt to clear space on the local ****** drive, I've "opted to hide some folders" according to the Selective Sync tab in Dropbox preferences. However, that folder is still downloaded to my local ****** drive and is located in the parent Dropbox folder. At this point, how should I remove it safely without disturbing the online version of the folder?

If Selective Sync has been activated you should not see them locally - so I would check before deleting anything that its fully updated and selective sync is set up. 

After that you could test a file or two and see if they also delete online or not just to be safe.
