[SOLVED]Trying to open a cfg file...

Hi! So, I'm trying to open up a cfg file(Config_mp) to be more precise so I can change the number of connection bars from 5-10. But I need a program or something to open it up with, yeah yeah sorry I'm computer clueless.

Notepad or Wordpad.
Tell me if it works.

I use notepad to edit mine.
Cleaner then wordpad.

Anyways open notepad.
Then drag and drop "Config_mp" onto notepad and settings should appear.
