 The default WhatsApp contact database typically contained contact names extracted from your phone, which the exporter used to map your chats. However, in some reported cases, the database may have never been populated. In such case, you can export your contacts to a vCard file from your phone or a cloud provider like Google Contacts. Then, install the necessary dependency and run the following command from the shell:

                        will be merged into the target directory. No chat messages or media will be
                        deleted from the target directory; only new chat messages and media will be added
                        to it. This enables chat messages and media to be deleted from the device to free
                        up space, while ensuring they are preserved in the exported backups.
  --source-dir SOURCE_DIR
                        Sets the source directory. Used for performing incremental merges.
  --target-dir TARGET_DIR
                        Sets the target directory. Used for performing incremental merges.
