How to split files into parts

I have a Powerbook G4 with 10.4.11 installed on it. I have a video file (16.78GB) that I want to transfer to my windows pc. Network is not an option, so I was thinking of a software to split the file into parts, and then to transfer it using a thumb drive. The problem is that i don't know of a software to split the file with. I have tried using Split&Contact but it wouldn't run on my system and it can't split files larger then 2gb. Do you have any ideas please it's urgent?

I've downloaded the software you suggested, but when I run it and put a file I want to split, there is a message " Calculating checksum of original..." and then it freezes so I have to force quit the program.
