Lorand said:But with large files zipping or rarring would take a long time and for example with video files no (or very little) compression is possible, it would be better a software that only splits the file, just like this one: http://jituonline.freeservers.com/splitfile.html (with this there's no need to have the program on the other end, because you can create an exe from the first splitted file for automerging).
