I upgraded my firmware to 2.02 and found that the P2P folder is now hidden from the volume. it appears as a separate network share (Volume_1/P2P or VOlume_2/P2P), so you can permission and map this from your PC. It's a pain, because I used to download to P2P and then move the resulting files to another location - now, I have to copy rather than move.
