Hej August!

 AA> I was relying on separate GNUWin32 programs before.

In linux those are all seperate supplied by coreutils, util-linux and other such packages.  I prefer them being seperate.

 AA> but the maximum split it supported was 2GB.  Busybox split
 AA> doesn't seem to have that limitation.

No suprise here.  Near as I can tell coreutils' split is only limited by free disk size and free memory.

Het leven is goed,
Maurice
