    What is it? Where did you get the file from?

    There is no well-defined answer to this. File extensions are not very reliable and nonstandard file extensions are completely hit and miss. Sounds like somebody copy/pasted an example with a generic extension from somewhere without understanding it.

    .ext can also be image files for example rendered by Maya or Blender (or other 3D modelling progs) but I'm not sure which programs can open them .. you might try gimp (Photoshop can but .. yeah ^^)

  • It's a file created by Norton for Windows. So, it's off-topic Oct 11, 2017 at 13:23

    @ArpitAgarwal not necessarily . Can you identify the file with file name_of_file.ext ? Plese start with one file and use the file name ratheer then foo.ext or *.ext or bar.ext .
