When you open a drawing, all xrefs update automatically. Use the Refresh Content (Reload) option from the Reference Manager to update xrefs whenever you want to ensure that the most current versions are displayed in your drawing.
Whenever you modify and save an externally referenced drawing in a network environment, other people can access your changes immediately by reloading the xrefs in their open drawings.
When you attach xrefs to a drawing, the program periodically checks whether the referenced files have changed since the last time the xrefs were loaded or reloaded. The XREFNOTIFY system variable controls xref notification.
