How do I compress and split files with terminal?

http://askubuntu.com – So what I wanted to do is compress files (using 7zip) and split a 600MB folder into 199MB parts, but sadly when I tried to do this task with archive manager it gave me an error, but I know that if I use terminal it will work. I looked this up in askubuntu and found out about this command: 7z a -v5m -mx0 ubuntu.7z I understand that v5m will split it to 5 mb parts and -mx0 means that it will not compress it, but I want it to compress so what should I write instead of this -mx0? Please note: I am using 7zip because I most probably will use this file on a Windows pc. (HowTos)
