is there any mysword "model book" out there so that we can open it with notepad++ to learn about the structure? thank you guys!
The answer to your question is, "No!"
MySword resources, like e-Sword resources, as well as theWord and perhaps other Bible Software, are database files, and not text based files. Notepad++ or any other (programming) text editor are able to read and edit database files.
If you want to learn about the structure of any of the resources files MySword uses (and this includes e-Sword) you need to have to have a Database program. For MySword (and/or e-Sword) resources, you will require SQLite, or SQLite Manager, or SQLite Browser.
