NSF-  The database file format utilized by the HCL/IBM Notes program, formerly known as Lotus Notes, is called.nsf, which stands for Notes Storage Facility. The format for storing various types of objects, including emails, documents, appointments, contacts, calendars, forms, and views, is defined.

PST – The PST (Personal Storage Table) format is supported by Microsoft Outlook for storing all mailbox data. Your emails and other Outlook objects are saved as an Outlook Data File (.pst) on your system. When creating an e-mail account from a web service provider, you can setup POP accounts, which download all of your emails from your web server and store them on your workstation. Users can keep their messages directly on their devices in a specified file using PST files. Users who really want quick and easy access to their messages without depending on an internet connection may find this helpful. PST files can also be utilized to backup your email correspondence.
