I bet there are some knobs to modify amount of buckets or other memory related settings in bzip2 to make work faster... if not, maybe another algorithm...but [bg]zip are so widespread they may become the one choice if you have to distribute the files to a wider audience. _________________________ {Beto|Norberto|Numard} Meijome "Everything should be made as simple as possible, but not simpler."
