Modifying the .Nk2 file

Question

 

Hi,

   I need to modify the .Nk2 file programatically in C#. I can view it's contents by using different tools but cannot modify it.

I think I need to decode it, store it in a readeable text file, which I can easily modify and then convert it back to .Nk2 file.

Is there any way in which I can programatically read and modify the .Nk2 file (without using any tool)?

 

Thanks,

Reshmi

Answer 1

The file format for the .nk2 file is undocumented, and Microsoft provides no APIs to access it. Therefore, if you want to modify that file, you'll need to do your own research to decipher the format, etc. -- essentially duplicating the work that the available third-party tools have done.

Thanks.
