Again with the old Sierra games:

You know how you wuld usually have to switch disks every couple of screens? I've got one of the 3-disk games, and I need to condense into just on directory on my hard drive. The install program won't work so I'm modifying a BATCH file from a similar game. If this can't work - does anyone know which files (like the vol.1 and vol.2 things) go where?
