Flag and other attribute utilities do not list the meta-data archive bit. This utility lists files in a subdirectory that have the meta-data archive bit set.
From the file server console type: metaarc.nlm VolumeName: path
example metaarc.nlm SYS: public
All of the files in public that have had their meta-data (modified time, trustees, attributes, etc) changed since the last archive will be listed in scan order.
