OneDrive: New Shortcuts folder option when adding shortcuts
OneDrive makes it easy to add shortcuts to the files and folders you use most. Now you can choose to keep those shortcuts neatly together in one place instead of mixed in with everything else. When you add a shortcut, you can send it to a dedicated “Shortcuts” folder rather than your OneDrive root. The folder is created automatically the first time you use it and is easy to spot, with a distinct color and building icon. The Shortcuts folder behaves like any other folder—move it, rename it, share it, or remove it whenever you like.
