.cfg file opener editor ? skymap

[Andrez]

I recommend Cubepad, it is specifically designed for editing cube-based .cfg files. You'll need to know how to extract from .tar.gz though, because it's currently only available through the SVN repository. Be warned, it's still in beta, so a few features may be missing.

here is a very noob question. what does SVN stand for ?
and another noob question(for other noobs too lol) is .tar.gz a website or a file type?

SVN = Subversion
.tar.gz is a filetype, like .zip, .rar, .7z and so on. You can open it by using 7Zip for example.
