the 1.2gb of space is for the nand backup. it will be a fairly large size. You can then move that to your pc and off of the card to return space againWait, QuantumCat told me CFW doesn't require much space at all. On the backup essential files section, it says you should have at least 1.2gb-1.3gb of storage on your SD card? I thought you didn't need much space at all?
