My idea is a personal project that I never published is another, Arc is not able to divide an archive, the basic concept that we all know, or nearly so, is to divide the input folder and then compress the parties as archive.
Arc during compression followed by a method therefore with different compressors, creates a temporary file "$$arcdatafile$$.tmp" which is the input data to be compressed, the second step is created a second temporary file "$$arcpackedfile$$.tmp" that creates the archive size, and it is this second file that should be divided into equal parts and in exact size, previously set, in order to create a set of split archives.
