Summary: Lotus Notes was one of the earliest office email, chat, and calendaring systems. In 1990, Lotus Development unveiled Lotus Notes, the program well known for its ground-breaking Lotus 1-2-3 spreadsheet. IBM eventually acquired the company. HCL Notes is the new name for Lotus Notes.

IBM Notes Software, formerly known as Lotus Notes, uses an extension file format called NSF file, which is also known as Notes Storage Facility. In essence, it establishes the schema for storing information such as papers, appointments, emails, and other types of data

In essence, NSF files are binary files made up of the following: a File Header, a Database Header, a Superblock, a Bitmap, a Record Relocation Vector bucket, a Summary bucket, and a non-summary bucket.

The ability to encrypt an NSF file in a variety of methods, including file encryption, port encryption, document encryption, database encryption, and mail encryption, is one of its finest features.

Let’s now locate the NSF file on your computer after learning everything there is to know about NSFs.

Where the NSF Files Are Stored Based on Windows

Keep in mind that the location of the NSF files will depend on the operating system if you need to check where they are. Furthermore, the server stores files in the NSF file format.

  • Windows: C\Programs Files\IBM\Lotus\Data
  • Windows XP: C\Documents and Settings\Username\Local Settings\Application Data\Lotus\Notes/Data
  • Windows Vista: C\Users\AppData\Local\Lotus\Notes\Data
  • Windows 7: C\Users\Username\AppData\Local\Lotus\Notes\Data
  • Windows 8: C\Users\Username\AppData\Local\Lotus\Notes\Data
  • Mac OS: ~Library/Application Support/Lotus Notes Data
  • Linux: /{$HOME}/Lotus/Notes/Data

Now that we are aware of where NSF files are kept, let’s explore the various types of NSF files.

Types of Lotus Notes NSF Files

NSF File for Mailbox – Mailbox.nsf is where you store data like tasks, calendars, and emails. Additionally, this file is located locally or on a server. This file has a lot of data, thus eventually it may grow enormous and surpass Lotus Notes’ Quota size limit. The program may then provide error messages like these when that occurs:

Names.nsf: This NSF file includes contacts, locations, and other information taken from a personal address book. The Notes folder contains an automatically generated file.

Other NSF Files: These are extra NSF files containing data about web browsers, bookmarks that have been saved, and other things. There are numerous file kinds, including

  • Bookmark.nsf: This file contains data on bookmarks that have been stored.
  • Perweb.nsf: It stores every piece of browser-related information.
  • Web.nsf: It includes a subscription to the Lotus Notes newsgroup.
  • Headline.nsf: This file stores information about database subscriptions.
  • busytime.nsf: The file busytime.nsf contains all the information on local free time subscriptions.

How to Use Lotus Notes to Access NSF Files

The steps to access NSF files in Lotus Notes will be covered in this section. Thus, follow the instructions.

  1. Launch IBM Notes and select File from the menu.
  2. Select Database and click Open now.
  3. Next, choose the server where the NSF file is stored, or local if the file is saved locally.
  4. Select the location of the NSF and press the Open button.

We’ll also talk about how to open a Lotus Notes.nsf file using an application other than Notes after this. Additionally, converting NSF files to PST is a simple process if you wish to view the data in Microsoft Outlook.

Methods for Opening NSF Files with Professional Application

As for the manual way of opening NSF files without Lotus Notes, well, there isn’t a way that can assist you with that. You cannot open this file because Lotus Notes is extremely safe and encrypted. This is the explanation for this.

Converting the NSF files to a different file type is your sole remaining option for solving the issue. The ability to save Lotus Notes emails as EML files is now available.

Therefore, you can select the Lotus Notes export option if you desire an EML file. However, there is a catch to this process: it takes a lot of time because you can only store individual emails at a time.

Try the CubexSoft NSF Converter Utility now to simplify the process; it provides various options for exporting NSF data into various file formats. You can use this tool to create files in PDF, MSG, EML, vCard HTML, ICS, CSV, and many other formats.

The utility also offers the ability to preserve the date filter and data integrity in addition to this. Additionally, the program has sophisticated conversion features including Internet Header, Header Doclink, HTML, Formatting, and Folder Hierarchy.
