Less is more
OneDrive's user interface is incredibly slick with its ample white space, minimalist typeface, and tile icons.
Keep it organized
Long-press on a folder or file to bring up options for sharing and keeping your OneDrive organized. I especially like how easy it is to move files between folders.
Because OneDrive is so tightly integrated with Office (and the rest of the Windows Phone OS), it's easy to quickly jump from viewing your files in the cloud, to editing them right there on your device.
OneDrive's slim toolbar can be expanded to show more options for sharing, searching, and otherwise keeping your cloud drive organized.
You can store your photos in OneDrive, and even have your Windows Phone automatically upload pictures you take to the cloud.
