Users need third-party software from the official eSoftTools website in order to extract data from the Lotus Notes database. This software provides several exporting file formats, including HTML, MSG, EML, EMLX, MBOX, and ETC, after extracting data from the Lotus Notes database. The software's greatest feature is that it can't alter the NSF file format's tree-like structure after conversion or extraction, and it only takes a short amount of time to convert a file into another format. The software may be downloaded for free from the internet.
