Edit description for 3DM template file

Hi,
we need to create a couple of 3DM template files. How do we edit the description box (see below)?
Not kidding - on first attempt we opened a 3DM file in Notepad++ and saw the text right there. Since then the 3DM files open in a non-readable format only - no idea what happened there.

Thanks for your suggestions!

Hi -

From the help file:

  • To add a description to a template file, type the description in the Notes panel before saving the template file. Start the note with the ’ (apostrophe), # (number/pound sign) or // (slash slash) character to prevent it from being copied into the new document created from the template. The description displays in the template list of the splash screen when Rhino starts.
