About NSF files

NSF files, or Notes Storage Facility files, are primarily used by IBM Lotus Notes, now known as HCL Notes. These files store emails, calendar entries, and other critical data. While powerful within the Lotus Notes ecosystem, NSF files can be challenging to manage outside of this environment. This limitation makes conversion a necessary option for users wanting to access their data through more common file formats.

One primary challenge with NSF files is their proprietary nature, which restricts compatibility with other software applications. Converting NSF files often requires specialized software like IBM Lotus Notes or Stellar Converter for NSF. These tools can help transform NSF files into more accessible formats like PST, EML, or MBOX, which are supported by email clients such as Microsoft Outlook and Mozilla Thunderbird. However, it's crucial to note that these software solutions may not be free and can be complex to use for novice users.

Important file extensions for conversion include:

Conversion can be challenging due to potential data loss, formatting errors, and the need for technical expertise. These drawbacks, coupled with the complexity of NSF files, underscore the importance of using reliable conversion tools.

The NSF Converter Story

The history of Convert.Guru began more than 25 years ago in California, when Tom Simondi published the most comprehensive database of file formats on his website. Before that, Tom had worked on Space Shuttle development at the Air Force Systems Command’s Space Division in Los Angeles. He is known as one of the top programmers of the late 1980s.

When Microsoft integrated Tom’s Filext database into Windows XP, it became the leading platform for analyzing and processing file types and formats.

Today, we use the latest technologies to analyze, process, and convert one of the world's largest collections of file formats. We are committed to developing the best NSF converter by continuously improving quality, usability, and reliability.
