Hi! I'm wondering if it absolutely necessary to copy n paste my SD card data when upgrading to a larger capacity card. I just went from 8gb to 32gb. From what I can see, all my apps seem to be functioning ok, even one's I've installed from apk files (downloaded and pasted from various sources) stored on my old card. Are there any essential system files on there that I should be aware of? I feels nice to be starting with a clean slate, so to speak.
