NSF

Lotus Notes Database

The NSF (Lotus Notes Storage Format) is a proprietary file format used by IBM Notes (formerly Lotus Notes) to store emails, documents, calendars, and other data in a database-like structure. It is primarily accessed through IBM Notes or HCL Notes, but third-party tools like NSF to PST converters or NSF viewers can also read and extract data. The format supports advanced features such as rich text, attachments, encryption, and replication, making it a robust solution for enterprise-level collaboration and data management.

XLTX

It is supported by Microsoft Excel, LibreOffice Calc, and other spreadsheet applications, enabling users to create, edit, and share templates across platforms.
