I've heard that you can move a game onto a thumb drive or the like, is it true? And where are the files to move?

As long as the removable storage is large enough, you can do it- the save game is found in the SI folder in My Documents in the Games folder.

Thanks alot, I've found it and can move it across to my work computer tommorow

whats a thumb drive?

USB stick/pen drive qpeter

thanks

could you send it tthrough email

Since the files would be quite big I wouldn't recommend it. I use thunderbird for my email and it has a limit on the size of files I can send (or maybe I haven't got it set up properly ). You could maybe try something like winrar or hjsplit to split the file into smaller parts and email each part the rejoin then once you get them at your destination.
