And only have selective sync available under preferences, please help, thanks in advance. I have tried it after Pausing Sync and that did not change anything. I cannot change anything to 'online-only.' That option is not available to me. I thought they would automatically be online-only, but when they started to sync they have almost totally filled my hard drive.
After upgrading to Dropbox Plus, with 2TB of space, I just transferred a lot of files and folders into my Dropbox.
