hello , eventhough i make extesion CSV , it is not csv, not comma seperated, not tab seperated , it is just plain file, because when you extract http://gb.archive.ubuntu.com/ubuntu/...6/Packages.bz2 file has no extension, so i make extension something else. So you can just open in simple text editor.
Actually i was just impress Ubunu Synaptic Package Manager , and just try for one step, but it is too far to be like that.
Anyway thanks for all replies.
