This tab displays items extracted out the box, such as documents, pictures, links, chats, and others. On the Artifacts tab, on the left pane, you should see Structure and Overview.
Under Structure, items are grouped based on their sources or locations. For example, if you add two different dumps or data sources containing chats for a case, Belkasoft X displays the chats under two different Instant Messenger nodes on Structure.
Under Overview, items are grouped based on their similarities. For example, if you add two different dumps or data sources containing chats, Belkasoft X displays all the messages for case—regardless of where they come from—under a single Chat node on Overview.
