Lotus Notes NSF File Location

Summary: IBM Lotus Notes is a popular enterprise email software that organizations use for business communication. The client-server software saves the users’ mailbox data in different NSF files. This post explains the NSF file format in detail and provided the default NSF file location in different OS. We have explained how to open NSF files and provided advanced software to open NSF files in other applications.


Lotus Notes NSF File Location

Many organizations use IBM Lotus Notes to manage business workflow through emails, contacts, calendars, etc. The software saves mailbox data in NSF file format, which stands for Notes Storage Facility. NSF files are database files supported by both IBM Lotus Notes (client software) and IBM Domino (server software).

What’s NSF File Location?

The default NSF location depends on your operating system and the installation performed. It’s important to note that NSF files can be stored both locally and on the server. If the files are stored locally, they are stored on the system on which the IBM Notes is installed. If the files are stored on the server, then they are stored on the Domino server.

NSF File Location Based on OS

The following are some of the default locations of NSF files for different Operating Systems:

  • 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

What are the Different Types of NSF Files?

Lotus Notes creates different NSF files for different data types- emails, calendars, contacts, etc. The two most important NSF files are mailbox.nsf and names.nsf.

Mailbox NSF File

Mailbox.nsf file stores the following data items: emails, tasks, calendar, etc. The NSF file location of mailbox.nsf can be both 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:

“Warning, database has exceeded its size warning threshold”.

To remove the error message, you need to remove duplicate emails from your mailbox, remove soft-deleted (trashed) mailbox items, etc. You can also move some emails and other data items to an archive file. The default Lotus Notes Archive file location is:

C:\Program Files\IBM\Notes\Data\Archive

Names NSF File

Names.nsf file stores data items related to personal address book including contacts, addresses, etc. You can create multiple names.nsf files in Lotus Notes by using the personal address book template- pernames.nsf file. Each file’s NSF file location is the default one, and these files can be named names2.nsf, names3.nsf, etc. You can also delete the names.nsf files when required. However, there have to be at least one names.nsf file for Lotus Notes application to run.

Other NSF Files

The following are some other NSF files that are used in Lotus Notes: bookmark.nsf, Internet.nsf, busytime.nsf, perweb.nsf, and headline.nsf. These files contain information related to saved bookmarks, newsgroup subscriptions, local free time subscriptions, web browsers, and Database Subscriptions.

How to Open NSF Files?

As mentioned earlier, the NSF file format is a specialized database format used by IBM Lotus Notes. So, you can open an NSF file only with Lotus Notes application.

To open an NSF file, follow these steps:

  1. Launch IBM Lotus Notes. Go to File > Database > Open.
  2. In the Open Database dialog box, select the server where the NSF file is located. If the file is saved locally, select Local
  3. Go to the NSF location and click Open
