Microsoft is rolling out some welcome improvements to its OneDrive cloud storage service today. While the company doubled its free OneDrive space in June and offered 1TB to Office 365 subscribers, Microsoft is letting OneDrive users take full advantage of the storage increases by allowing files up to 10GB to be uploaded to the service. Alongside the upload changes, Microsoft is increasing the number of files than can be downloaded or uploaded to OneDrive at the same time on PCs and Macs.
