Review Comment:
How about add a little more clarity, `` To show all files, data files, and
delete files across all tracked snapshots, query all_files, all_data_files, and
all_delete_files respectively.``

Review Comment:
'inspected individually' sounds like querying about one file, which is not
the case.
How about: `` To show only data files or delete files, query 'data_files'
and 'delete_files' respectively.``
Then it matches the below sentence.
