This is certainly an interesting tool, and looks to me to be very similar to backup/restore. But I'm not sure if this thing will potentially split individual files input files acress multiple output archive volumes. (If it might do so, then this violates part of my original problem statement.) Also, I am guessing that this thing produces outputs that are encoded into its own unique output archive format. Ideally, I just want to end up with individual (temporary) directories, each one full of up to 23.3 GiB worth of ordinary files. Then I can tell ImgBurn to -directly- generate and burn that set of files, as a UDF image, to optical media. This way, I won't need any special tools or software if I ever want to get back any one of the files that have been archived. I can just plop the relevant (burned) BD-R into a Blu-Ray drive, and no matter what OS that is attached to... e.g. FreeBSD, Linux, or even Windoze... I can just directly copy off the one file I want, because all of these comon operating systems directly support the UDF file system. Regards, rfg
