I don't believe there is an automated way to do this. I think clever use of the DiskId attribute of the "directory" element is probably the easiest, assuming the files are split up into a few directories. On the other hand, if all (or most) of the files do go to the same directory, then I don't believe there is an automated way to do (unless you create your own program).

Hi Mike, I have about 10,000 files and it appears they are all but in the same cab. Is there way to specify in an automated fashion to split the file in an equal number of cabs?
