I think when you asked how to edit a file, you may have left some with the impression that you aren't yet ready for a full hd install.
I have already installed knoppix in my hardrive with ext3, but somebody wrote that reiserfs is faster than ext3! This is the reason why I want to go for reiserfs type installation.
I think I will have to study more the commands; this is something really new for me!

Thank You.
