Don't waste any cd just put all 4 of them into 1 cd and install it. Create the install script and put all 4 apps into it. Here is the example. Name it as INSTALL.CFG.
APP1
mc0:BOOT/APP1
MD mc0:BOOT
CP cdrom0:\APP1;1 mc0:BOOT/APP1
APP2
mc0:BOOT/APP2
MD mc0:BOOT
CP cdrom0:\APP2;1 mc0:BOOT/APP2
APP3
mc0:BOOT/APP3
MD mc0:BOOT
CP cdrom0:\APP3;1 mc0:BOOT/APP3
APP4
mc0:BOOT/APP4
MD mc0:BOOT
CP cdrom0:\APP4;1 mc0:BOOT/APP4
Infinity Manager can only have 5 apps max that why I don't like it. I'm using DMS HDD Explorer with my MI, much better.
Here is my screenshot
