OneDrive is Microsoft’s cloud-based data repository and every Microsoft account includes a minimum of 15 GB of free OneDrive space. You can manually upload files to your OneDrive space or you can install Microsoft’s OneDrive app on your Mac, Windows computer, laptop, tablet or phone and sync files between your online OneDrive space and all your devices (there are compatible apps for Windows-, Android- and iOS-based devices).
Your OneDrive space can be your own private data repository or you can use it to collaborate with your friends, family members, clubs, groups, coworkers, or customers by sharing your OneDrive folders and files with other people. When you share folders or files with others, you also set permissions that define how the shared files can be accessed by others. You can grant permission to others to only view the files or you can grant permission to view and edit the files.
