@sigmatador : what is so funny ? author's location doesn't realy matter here ...
@31flavas : you are right , this is simple to program for. But simple doesn't mean simplistic and that's good for me because i'm still_bad_but_learning C (i do maple scripts for computer algebra as a job and i knew quite nothing in C 6months ago).
rv9 video and rmfactory feets all my needs and whishes for 1 cd dvd backups and that's what i wanted
i did my own programming cause i just always say 'how to do this and that ?' and really love to find a good solution...also remember we french are the people who work the less (35h/week)
