Differential sync, a feature that's been in the pipeline for some time, is slated to come to OneDrive this spring. In a recently updated OneDrive product roadmap reported by ZDNet, Microsoft pegs the feature for a Q2 2017 release.

OneDrive Roadmap 2017

For those unfamiliar with differential sync, it's a feature that would allow OneDrive to sync only the parts of files that have changed, rather than re-uploading the files in their entirety. The net result is that the app should use less bandwidth when syncing changes across devices.

The addition of differential sync has been in the plans for some time, thought the January update to the roadmap is the first time it has been given a firm release window. Other notable upcoming bits outlined by the roadmap include auto-tagging for photos, optical character recognition and whiteboard cleanup, and more.
