I have problems to split files bigger then 2 Gigabyte with split 2. also gzip and bzip2 were not helpful with files bigger then 4 Gigabyte. - with zsplit/unzsplit on the same machine, same kernel I can effectively treat files/devices as big as 200 Gigabyte and for sure even bigger. 3. with different tools combined in scripts you cannot have a good control about progress in zipping and splitting files in chunks. 4. to use one tool which combines features of different tools is easier to use in scripts the combination of tools. So as you can see new is here not an idea of imaging, but the combination of features in one tool. Regards, Jurij
