You have opened a page in the graphical editor.Insert > Graphic > Hyperlink. In the Properties dialog, select the document to be linked on the Hyperlink tab and click [OK].
In this dialog, you can specify whether the document is to be copied into the project directory or referenced from the source directory.
The following dialog elements are available:
A reference to the document is inserted in the project. If the document is changed, it is automatically updated as soon as you open the page. However, referenced files are not included in backups.
The document is copied into the project directory (that is, into the external document subdirectory of the project). All files in the project subdirectories are also included in backups.
Select this check box to have a confirmation displayed for the Copy option if the document is already present in the project directory. You can then decide whether it should be overwritten or not.
