Store your stuff in the clouds. You don't need to worry about freeing memory for your favourites or new apps.
SkyDrive is cloud storage for all your documents and photos, so you can access, share, or restore them if need be.
With SkyDrive, you can access your photos, documents, and more from your phone, tablet, or computer. Depending on the app, you can even continue working on a document right from where you left it earlier.
There are several places where you can access your stuff on SkyDrive. For example, you can save photos to SkyDrive in the Pictures hub, or manage your office documents in the Office hub.
To easily manage your stuff in the cloud on your phone, you can download the SkyDrive app from Marketplace.
