-Update: This is only for information purposes, I know that just renaming the floppy's volume name will not install the other keen episodes.
I have a special set that includes both Keen 4 and Keen 6 v.1.5
This volume name for the floppy is KEEN S X-3,
where x is the number for the current floppy disk in the drive.
My Older Keen 6 disk has a volume label KEEN 6 X/2,
where x is the number for the current floppy disk in the drive.
I am just curious to see what the other volume names are for
the keen series. The same install.exe seems to have been used for every game. Renaming a floppy disks volume to KEEN 1-2 prompts for a disk to install Episode 1.
So if anyone would be willing to check their old keen discs it would be appreciated.
