A relative hyperlink contains only a portion of the information Visio needs in order to locate the target of the hyperlink. To reach the target object, Visio must combine the partial information in the relative link with the hyperlink base, as shown below.
Hint: The choice of Relative or Absolute path is not available until you have saved your TaskMap for the first time.

For better or worse, this topic gets a bit technical but once you understand the basics, you’ll be able to take advantage of the considerable flexibility that relative hyperlinks provide.
