Explorer

I see in the Explorer user guide that the following zone files (and others) are suppose to get collected but when I run explorer and search the output I see very limited zone infomation collected and none of the list below.Am I missing something or could this be a bug?
I'm running whole root zones, could that be the issue?

${ZONEPATH}/root/etc/TIMEZONE
${ZONEPATH}/root/etc/atuomaster
${ZONEPATH}/root/etc/hosts
${ZONEPATH}/root/etc/inetd.conf
${ZONEPATH}/root/etc/defaultdomain
${ZONEPATH}/root/etc/defaultrouter
${ZONEPATH}/root/etc/dumpdates
${ZONEPATH}/root/etc/coreadm.conf
${ZONEPATH}/root/etc/ethers
${ZONEPATH}/root/etc/fcswitch.conf
