Microsoft raises OneDrive file size upload limit to 250 GB

Microsoft is increasing the upload file size limit for its OneDrive file storage service to 250 GB, compared to the previous limit of 100 GB, the company announced.

Microsoft says it is making the move to recognize the increase in remote work and learning, where users need to reliably and securely share large files like 4K or 8K video files, 3D models, CAD files or large scientific data sets with coworkers, customers and colleagues.

We are pleased to announce that we are making it easier than ever to store, sync and share large files in Microsoft 365. Our latest enhancement will help increase the upload file size limit for Microsoft 365 from 100 GB to 250 GB— which includes file uploads to SharePoint, Teams and OneDrive. You will now be able to easily share large files, such as a 3D model of a new building, a customer commercial shot on 8K video, a large data set for a vaccine test or research projects, or large videos for educational projects.

Microsoft explained that the move is not limited to business and school users – anyone using OneDrive can now take advantage of the new 250 GB file size limit for uploading things like video albums and large game files.

The company says it has managed to increase the upload limit by dividing each file into parts, with each part encrypted with a unique key. In addition, synchronization of large files has been optimized with the help of differential synchronization, which only loads changes made by users to the stored file.

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