If you move, rename or delete a document that is a link destination all hyperlinks to it will be "broken". You can check the map for broken links to files and folders.
This command does not check links to web sites or other web locations or to Mindjet Catalyst workspace documents.
On the Home tab, in the Topic Elements group, click the Hyperlink arrow, and then click Check File & Folder Hyperlinks.
If a broken link is found, you can choose to browse for the file to repair the link or remove the link from the map.
If you click a broken hyperlink you'll get a message that offers you the opportunity to repair it immediately.
