Can the ASR & JCV files all go in the "Same" folder, or do they each need their own folder?

ie: I have used Mapsource to send the CNE maps to my Micro-SD card on my 885, now I have to copy over the JCV files.

Do I create ANOTHER JCV folder on the SD card or copy the CNE JCV files into the JCV folder on the main unit that was created when I loaded the CNNA maps using the Garmin Map Updater ?
