I am using Excel 2007 and have set up a series of charts to autopublish to
web pages each time the workbook is saved. I relocated the destination
folders and now what to update the links to these folders in excel. Since I
have a large (50) number of charts, I would like to be able to edit the links
directly rather than setting up each chart to auto publish again.

Where does Excel store the links that are utilized in the publish function?
