Ah, I guess that's why you have to run "apt-file update" on Debian to
get it. It's not there by default.

I checked one of the files that it downloads (Contents-amd64.gz).
That's a 32 MiB file that when extracted becomes a 480 MiB plain text
file. So it's comparable to your figure -- apt-file downloads a few of
these files (one per apt repository).

However, apt-file never extracts the files, it simply runs zfgrep on
the ~32 MiB sized .gz files. So it's not that bad.
