WMV file size

I have had excellent success using the Windows Media Encoder to convert AVI's for my iPAQ. Quality is pretty good.<br>My question is whether there is a good method to split large movie files into two pieces. I find that I cannot fit most long movies onto a 128MB CF card. They tend to run around 130-140MB. Is there software available to split these so I can put them on two different CF cards.<br>TANSTAAFL!
