Have you ever come across an NSV file and don’t know how to open it? Bingo! You’ve come to the right place.

What is an .NSV file?

NSV, the abbreviation of Nullsoft Streaming Video, is a media container designed for streaming video content over the internet. It was developed by Nullsoft, the makers of Winamp. However, the NSV file is not a commonly used video format and many video players don’t support it. It’s really frustrating when we double-click an NSV file and the OS says it can’t be done!

Ways to open an NSV file

Here comes the cure. Normally, there are two ways of opening NSV files.

The first one is to have a powerful media player installed on the computer, which can solve all of your problems with opening NSV files.

The second one is to convert the NSV files to some common video formats, such as AVI, WMV, MPEG, by video converter software.

Now, are you looking forward to trying it? Just hang on, because there are still some small issues to deal with before we try it:

  • Make sure the NSV file is registered in the registry;
  • Make sure the NSV file is not damaged or infected;
  • Make sure the divers of your equipment used to open an NSV file are up-to-date;

If you are sure of the above issues, then let’s do it!
