The options for file space are called Free, Medium and Premium. The free

version will offer all younited’s functionality along with 10 GB of safe

cloud storage – but only for a limited time (starting 2014, the free

version will offer 5 GB). Medium expands safe cloud storage to 200 GB

safe cloud storage, retailing at € 120 a year.
