Managing iCloud Storage
I received a notice that I need to increase my iCloud storage because I am running out. I went into my iCloud. my iCloud mail has a grand total of 3 emails ( I don't use that account). iCloud photos has a total of 6 photos. (I don't use iCloud photos to back up my photos). There are no videos, no books, nothing in iCloud Drive. Yet I am using almost 3gigs of capacity in iCloud.
How can I find out what is using up all the capacity?
And how can I manage whatever is there?
