A very small application for splitting (and joining back) files. Fully functional - splits by count of parts or by size, runs from command line, supports drag and drop... Actually I wrote it when one my fellow found elsewhere such program and told that it weighed "only" 24K. Then I wrote my own which weighed 18.
Please, take it at here:
