Attachments To Calendar Events
You can attach files to events in the calendar, providing enhanced coordination for documents associated with events.
When you are creating a new calendar event, from the Add additional details page, check the Attach Document box towards the bottom of the window (and enter any other necessary details), then click the Create button.
Either drag and drop the particular file(s) into the dotted line box or click the Select files button and choose the files from their location on your computer then click the Upload button.
A calendar event that has attached documents will have a paper clip icon next to it when viewed in the month, week or day views.
