The Files on Computers tab shows all instances of the files in this notification in the Carbon Black App Control Server file inventory.
This can include (either by default or customization) all fields from the console Files On Computers page. You also can add External File Name and External Size columns. The Action menu has the same options as the Total Files tab menu.
You can modify Correlation Details options on this page to customize the Carbon Black App Control data correlated with the notification (this affects all pages that display correlation options).
