If you have a Box account (https://www.box.com), the Box widget shares a single file or folder from that account to Space members. The file or folder appears to members inside the working area, with the same controls as if they were accessing it directly from Box.
Click the Launch Box Chooser button to launch the Box chooser to choose a file or folder to share. The chosen file appears beneath the work area.
You can share only one file or folder at a time with this widget. If you edit the widget and change it, the new object replaces the old one.
