it's cool. all you need to do is open a mod, hit the 'explore right' button, copy all that stuff, and open the other mod, then hit 'explore right' and paste it.
hitting the 'explore left' opens all the default unedited files in the game
hitting the 'explore right' opens all the modded files that belong to the mod you opened
all of the files are stored on your hard drive.
and this is how to access them.
you can edit these files through the 'explore right' button if you want, i do because i like notepad better than the sporemaster program anyways.
