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