Microsoft is increasing the upload limit of OneDrive files to 250 GB

Microsoft is increasing the maximum file size of its OneDrive file storage service to 250 GB, up from the previous 100 GB limit, the company announced.

Microsoft says it is making the change to recognize the proliferation of remote working and learning, requiring users to reliably and securely share large files such as 4K or 8K video files, 3D models, CAD files or large scientific datasets with colleagues parts, customers and colleagues.

We are pleased to announce that we are making it easier than ever for you to store, sync and share large files in Microsoft 365. Our latest enhancement will help increase the maximum file size for uploading Microsoft 365 from 100 GB to 250 GB — including file uploads to SharePoint, Teams and OneDrive. So now you can easily share large files such as a 3D model of a new building, a commercial recording of a client in 8K video, a large dataset for a vaccine trial or research projects or large videos for educational projects.

Microsoft explained that the change isn’t limited to business and school users – anyone using OneDrive can now take advantage of the new 250GB limit for uploading things like video albums and large game files.

The company says it has managed to increase the upload limit by splitting each file into pieces, with each piece encrypted with a unique key. In addition, synchronizing large files has been optimized using differential sync, uploading only the changes users have made to the saved file.

Support for the new 250 GB file size upload will be rolling out in late January, and Microsoft expects general availability of the new limit by the end of this quarter.
