Create Artifact For External File
You can create an Artifact element on a diagram for an external file, by clicking on the file in a file list (such as Windows Explorer) or on your Desktop and dragging it onto the diagram. A short context menu displays with two options - Hyperlink and Artifact.
Click on the Artifact option to create the element on the diagram.
The element Properties dialog displays, and you can enter the element's name and other properties as required.
Click on the OK button, and then open the Properties dialog again and click on the Files tab. The file pathname is listed in the Files panel.
