What is a .nsv file?
A .nsv file is a nullSoft video. Its registered MIME type is video/x-nsv, which places it in the video family of formats.
NSV is a binary format: the contents are not readable text, so opening it in a text editor shows scrambled characters.
Files of this type usually begin with the bytes 4E 53 56 66. That signature is how programs recognise the format even when the extension is wrong or missing.
