NSF file which is also known as (Notes Storage Facility) is an extension file format used by IBM Notes Software which is formally known as Lotus Notes. Basically, it defines the schema to store the data such as emails, appointments, documents, and other data.

Basically, the NSF files are binary in nature and consist of File Header, Database Header along with that it also consists Superblock, Bucket descriptor block, Bitmap, Record Relocation Vector bucket, Summary bucket, and Non-summary bucket.

The best about the NSF file is that it can be encrypted in many ways such as Filed Encryption, Port Encryption, Document Encryption, Database Encryption, and Mail Encryption.

Now after knowing all about the NSF let’s find out where is the location of the NSF file in your machine.

Location of the NSF Files Based on OS

Well, the location of the NSF file is totally dependent on the Operating System you are using. And also remember that NSF files are stored locally as well as on the server.

Windows 7, 8, 10: C\Users\Username\AppData\Local\Lotus\Notes\Data

Mac OS: Library/Application Support/Lotus Notes Data

Linux: /{$HOME}/Lotus/Notes/Data

Now, after knowing the location of NSF files let’s find out what are the types of NSF files.

Types of NSF Files

Mailbox NSF File – Well, Mailbox.nsf stores emails, tasks, calendar, etc. And the location of this file is also local or server-based. This file stores lots of data, which is why after a point, it can become large-sized and reach the Quota size set in Lotus Notes. When that happens, the application may display error messages such as:

Names.nsf – This NSF file contains data from a personal address book, such as contacts, locales, and so on. This file is created automatically in the Notes folder.

Other NSF Files – These are supplementary NSF files that include information such as stored bookmarks, web browser information, and so on. There are a variety of file types, such as,

  • Bookmark.nsf – It stores the information about saved bookmarks.
  • Internet.nsf – It contains Lotus Notes newsgroup subscription.
  • Perweb.nsf – It saves all data about the web browser.
  • Headline.nsf – It saves data about the Database subscriptions information.
  • Busytime.nsf – It saves all data about local free time subscriptions.

Now to solve this you have only one option left is to convert the NSF files to some other file format. Now, Lotus Notes gives you the option to save Lotus Notes emails as EML files.

So if you want an EML file then you can use the Lotus Notes export option. But there is a catch in this process that you can only save individual emails at once which makes this method so time-winded.
