When you run a "Who has access where?" report on a folder it will report on all child directories (if scanned properly).
If not, you either have the level set differently:
0 (Zero) would mean only the selected folder.
And/Or have this (default) option active:
I would NOT recommend deactivating this.
What this does: if it only shows the selected path, then all permissions of the child directories are the same. If it shows more paths, then they have a different set of permissions.
This is a quick way to see if something is different and makes the report way more readable - or do you want to check manually several (potentially hundreds) of pages if there's something different?
