Find direct and indirect links between artifacts such as USB devices, internet downloads, file access, emails, and documents.

Items can be shown in the Links graph. This is done by highlighting the item and clicking on the 'Add to links graph' button. W4 will then switch to the Links tab where you can see the links for the selected item. In this image, we can see that the document has links to the C: drive of the system as well as a USB device.
