# Rick :
You'll need to unPBO the mission files in order to open the mission.sqm or other relevant files in notepad for editing.
You can google up the tool for unPBOing the files. One's you've finished editing, just repack them into a PBO again.
I'm sure it is probably a simple response and I can probably go google it, but since you mentioned it. I already have the files opened in notepad which is where I have edited them. My problem now is saving them back into .pbo
