DVR recordings. Storage Quota the service offers 5 GB of free storage for new users. Additional storage is available for purchase. The amount of storage available has changed several times. Initially, the service provided 7 GB of storage and, for one year, an additional 3 GB of free storage to students. Users who signed up to OneDrive prior to April 22, 2012 were able to opt-in for a limited time offer of 25 GB of free storage upgrade. The service is built using HTML5 technologies, and files up to 300 MB can be uploaded via drag and drop into the web browser, or up to 10 GB via the OneDrive desktop application for Microsoft Windows and OS X. From September 23, 2013 onwards, in addition to 7 GB of free storage (or 25 GB for users eligible for the free upgrade), power users who required more storage could choose from one of four paid storage plans. Users in some regions may need to have a certain payment card or PayPal account to pay. The paid storage plan is renewed automatically each year unless Microsoft or the user cancels the service. Upon the re-launch as OneDrive, monthly payment plans were introduced, along with the ability to earn up to 5 GB of free storage for referring new users to OneDrive (500 MB each), and 3 GB if users enable automatic uploads of photos using the OneDrive mobile apps on smartphones. Subscribers to Office 365's home-oriented plans also receive additional storage for use with the service, with 20 GB per user. In June 2014 it was announced that OneDrive's default storage would increase to 15 GB, putting it in line with its competitor Google Drive. An additional 15 GB were offered for activating camera roll backup on a mobile device, putting it ahead of Google Drive until November 2015, when this bonus was cancelled. The amount of additional storage for Office 365 subscribers also increased to 1 TB. Microsoft reduced the price of OneDrive storage subscriptions at that time. In October 2014 Microsoft announced that it would offer unlimited OneDrive storage to all Office 365 subscribers. However, on November 3, 2015, the 1 TB cap was reinstated. Microsoft additionally announced the planned replacement of its 100 GB and 200 GB plans with a new 50 GB plan in early 2016, and the reduction of free storage from 15 GB to 5 GB.
