You can link selected text to files or web sites outside of your NVivo project—these links are called 'hyperlinks'. If web site addresses change or files are moved, hyperlinks will become invalid.
It is a good idea to create a folder for storing files that you want to link to—this makes them easy to identify when copying your project.
Hyperlinks are broken when the destination file has been moved, renamed or deleted. If the link occurs in many source documents, you need to fix the link for each occurrence.
NVivo addresses this problem by providing 'externals' to handle hyperlinks. You create one external to represent the web site or file and link to the external from other documents—this way if a hyperlink becomes invalid you need only update it in one location.
To handle hyperlinks using externals:
Create an external to represent the web site or other file.
Create a 'See Also' link from the required content to the external.
To open the file from the 'See Also' link:
Click in the 'See Also' link and click the Links menu.
Click the Open Linked External file option.
