[HELP] How do I make my VB2k8 Program open and edit .ff files?

[RoonScape2]

I'm trying to make a VB2008 Program that will open and edit a .ff File, but I have no idea how to go about it.

I think I may need to make my VB Program open up a program called ".FF Viewer", but not make the users see it.

What I need to do is make a program that
1. Opens .ff files
2. Opens sub-folders in .ff files
3. Edits script in the .ff files by hitting buttons, e.g "CheckBox1", if ticked will enter a certain script into the file.
4. Saves the file
If you've ever used .ff Viewer, you'll know that you can open up the files, sub-folders, etc, edit the script, etc, etc. But what I need to make is a program that enters the script by just ticking a box off on the program, without it showing the people that .ff Viewer is open.

So, how do I make it open .ff folders using .ff Viewer and without showing the .ff Viewer window, open sub-folders in there, make checkboxes, when ticked, edit the script and save?

Muchos Gracias to whoever tells me

You will first need to know how .ff files (whatever the hell they are) are set out. Also, wrong section.
