Looking for ISO splitter

[Ratatapa]

Hi I need a good software to split a big ISO into 2 parts

Which one would you recommend

What do you mean? You could open the iso up and copy the files out (it's mostly a container), or if you needed to keep the full physical/file structure intact (say a music cd with data tracks), you could use any zip program to create a split archive with any sized chunks. The archive can then be recombined at some other point in time.
