Google, in its blog post, has launched an “Inactive Account Manager” (“not a great name, we know,” Google said) page that can be used as your digital will.
Google asks you what you would like to do with your images, files and other virtual data when you stop using your account for a long period of time, i.e after 3, 6, 9 months or 1 year. This service covers all Google accounts, +1s; Blogger; Contacts and Circles; Drive; Gmail; Google+ Profiles, Pages and Streams; Picasa Web Albums; Google Voice and YouTube.
