Hi all,

I've done a search for similar posts but nothing has really answed my problem.

A teacher has several smartboard files which have the extension .nbk. We have promethean boards with activinspire. Now I know inspire can open smart notebook files, but this only seems to be .xbk and .notebook.

My questions are:

Is .nbk a newer file format that inspire wont open or is it an old file format that no one bothers with anymore.


Is there any free way of opening a .nbk file (I've tried Smart Notebook Express but this will only open .notebook files).

Any ideas anyone?
