title: Viewing binary files in MSVS under Windows 10
body: <p>For ages I've been using MS visual studio 15 to view binary files, simply by doing file|open. My files have a custom extension, 'SQ3', but VS seemed to happily infer that they aren't text, and display them as binary. However, Win10 seems to have stopped that. Now if I do the same thing, a popup appears, asking me whether I want to find an application from the shop, or always use this application (presumably MSVS, the one I'm invoking from). There's a proceed button, but it doesn't respond. There seems to be no way that I can get VS to open and display the file. </p>
  
  <p>Is there a way to stop the OS intervening so VS can do its thing? </p>
  
  <p>Incidentally, having to rename files would be extremely inconvenient in this situation.  TIA</p>
  
  <p>Thanks, that's perfect.</p>
