Well my sense is that Apple has greatly expanded the support of Chinese
features. They are of no use t me so I'd like to delete them and recover the SSD space.
Do I need to go hunting or is there a specific China group of files?
Yes. XSlimmer is a similar application that removes PowerPC code. It claims to remove about 1GB of space (out of about 8GB of applications) on my Mac. I haven't run it yet since I have 60GB free.
