I ran across two questions which are marked as duplicates, but which appear to be asking slightly different questions (I say "appear" since the wording is ambiguous), and whose answers are answering those respective questions:
As asked and answered, the first question appears to be asking how to view the list of files within a ZIP archive. The second appears to be how to view the contents of a file within a ZIP archive. The solution to these is very different, as is evident by the top-voted answer in each.
It seems like the "duplicate" question should be reopened, and its wording clarified to reflect the difference.
