As a newbie to Macs I thought putting files into iCloud would save me SSD space, but now I see that is not the case. I also have Dropbox and I was wondering if there is a way to transfer files from iCloud to Dropbox and use Dropbox's selective sync option to keep some of the files stored there from cluttering up my SSD.
