Right-click (or press Ctrl and click) on filenames in the Assets panel to see the context menu appear. If you've used Adobe InDesign, this panel is called the Links Panel.
The Assets panel context menu contains the following options:
Relink: This option lets you reconnect files that have been moved after they were placed on the page. When you click on this option, use the Relink window that appears, to navigate to the file, and select it to specify its new location to Muse.
