NS1 file extension format:

To view or edit NS1 files you need to know the file format, because it determines how the data in this file is stored. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our evaluation of the NS1 files is as follows:
