About NTS files
The .NTS extension refers to three distinct file types, creating frequent confusion for users.
NTSYS-pc Data Matrix: The most common technical use is for Numerical Taxonomy System files. These are plain text matrices used by NTSYS-pc to analyze biological and morphometric data.
PVR Video Index: Set-top boxes (like Humax or those with ALi chipsets) generate .NTS files alongside video recordings.
Legacy Documents: Older versions of WordPerfect used this format for note documents.
The Problem: Users often deal with issues because these formats are incompatible with standard software.
Scientific Users: Opening an NTSYS matrix in Microsoft Excel is difficult because the file contains strict headers and formatting rules that cause import errors.
Video Users: Many users attempt to play .NTS files in media players like VLC, believing them to be video files. In reality, these are small index files (often under 100KB) that contain navigation data, not the video itself. They are useless without the accompanying TS or DVR file.
Legacy Users: Old WordPerfect notes are proprietary and cannot be opened by modern word processors like Word or Google Docs.
The Solution:
For Data: Convert NTSYS files to CSV or XLSX format to manipulate the matrix in standard spreadsheet software.
For Video: You cannot convert an .NTS file to MP4 directly because it contains no video data. Instead, locate the matching TS file and convert that to MP4 or MKV for playback on PC/Mobile.
For Documents: Convert legacy notes to PDF or TXT to archive and view the content.

The NTS Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NTS converter.
