Have given up with Dropbox - way too confusing now.
I couldn't work out when dropbox deleted from the cloud and / or my home PC.
e.g. I saved a new folder onto desktop - and then saw it also oddly listed in my dropbox folder (why did it mirror the desktop but not the other drives on my pc?) - so I deleted it there - only to find the folder now also deleted on the desktop.
GDrive far easier to manage.
