Microsoft has announced the global availability of OneDrive, the cloud storage service formally known as SkyDrive.

At the same time, the Redmond developers has also published the updated mobile apps on various stores including Windows Phone 8, iOS and Android, in addition to desktop apps for Windows and Mac OS. As SkyDrive was natively integrated in Windows 8.1 and Xbox One, the Update 1 for Windows 8.1 and a Xbox One update scheduled for March will bring OneDrive.

Now users will be able to increase the storage space by inviting their friends, just like Dropbox and enabling auto-upload of photos on their devices.

For those users who have been using SkyDrive, won’t have to do anything as they will find their documents, photos and videos at the same place. However, newcomers can access the service through the official website OneDrive.com or installing apps for desktop, tablets and smartphones.

Microsoft touts again that the new name reflects the company’s vision for the future: “Our goal is to make it as easy as possible for you to get all of your favorite stuff in one place—one place that is accessible via all of the devices you use every day, at home and at work.”

To achieve this goal, OneDrive app for Android has integrated support to upload photos automatically (already available on iOS and Windows Phone). In addition, OneDrive will transcode videos automatically – regardless the video format – by calculating and analyzing video properties based on your Internet connection. It will reduce the bandwidth consumption on different devices.

OneDrive offers 7 GB of free space (25 GB for old SkyDrive users), and you can get up to 5GB of additional space, inviting 10 friends. For each friend who registers will receive 500 MB. Moreover, if you enable the auto-backup option for photos on Windows 8.1, Windows Phone, iOS and Android, you can earn 3GB more. Besides who wants more space can subscribe to an annual subscription too (additional 50GB for $25; 100GB for $50 and 200GB for $100).

To celebrate the launch of OneDrive, Microsoft is also giving away 100GB of free space for 1 year to 100,000 lucky users. To know more about the promotion, simply follow @OneDrive on Twitter.
