What is an NST file?
An .NST file is primarily a data file. It has three common uses.
First, it is an Outlook Group Storage File. Microsoft Outlook uses this format to store Office 365 Groups data locally on your computer. It works like an .OST or .PST file. It can also act as an Outlook Connector for Notes file, helping Outlook communicate with IBM Lotus Notes.
Second, an .NST file is a NIST Biometric Data Interchange file. The National Institute of Standards and Technology created this format to store and share fingerprint and facial data securely.
Third, it is a NoiseTracker Module, which is an old audio format used for tracker music.
How to open NST files?
Microsoft Outlook opens and manages Outlook storage .NST files automatically. You do not need to open them manually. To open NIST biometric .NST files, you need specialized tools like NIST Biometric Image Software.
Inspecting files online
viewer.online/nst can analyze .NST files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available. Because the .NST extension has multiple possible meanings, we recommend using viewer.online/nst to identify the actual format of your file.
Converting your files
We recommend file conversion to sensible target formats on convert.guru. You can often convert audio tracker .NST files to standard formats like .MP3.
Summary
viewer.online/nst is useful for identifying, inspecting, and understanding .NST files without installing software or dealing with compatibility problems.
