Where is the set of what you call "timezone files" defined?

ftp://ftp.iana.org/tz/code/Theory talks of
"time zone rule files" and singular:

"The daylight saving time rules to be used
for a particular time zone are encoded in the time zone file"

No "time zone files" or "timezone files" found.

So, the benefits layed down at
and other unknown reason that lead to multiple white space in some
files are out-weighted by something unknown for zone.tab? What could
that be?
