Hi,
Visiting a large zip file to list the contents of the zip file
doesn't work if the zip file size exceeds the emacs buffer size
limit.
Obviously this is not the way it should work since the zip file
content doesn't need to be read into the buffer.
Is there a fix for this?

In my setup the variable auto-mode-alist says that ZIP files are
handled by archive-mode. This is defined in arc-mode.el. Right at
the top of that file is a table that indicates that viewing is an
*internal* operation for all archive file types. So Emacs does
actually need to read the file to interpret it.
I haven't found a way to use external tools instead in arc-mode.el.
Sorry, benny

Actually, the Emacs mode that supports operations on *.zip files
_does_ read the whole zip file into a buffer; hence the problem.

But I think Kin's point still holds: Emacs does not *need* to read
the file, since it uses external tools to extract/list/...
Contrary to tar-mode, for example.

I'm guessing that whoever wrote arc-mode tried to avoid external tools as
much as they could, since some of the wide-spread tools are not free
software, and the free ones might not be installed. Also, IIRC arc-mode
allows you to edit the file's attributes in ways that might be
impossible with external tools.
Anyway, if someone wants to rewrite those parts of arc-mode to use
external tools, or perhaps fall back on that if the file's size is too
large for Emacs, I'm sure that would be a welcome addition.

tar-mode _could_ do the same (i.e. use the external `tar' program).

Technically it doesn't. Emacs simply opens the file to determine the
contents by itself. If it didn't do this it would have to deal with
the different switches used by various "unzip" programs out there to
list the contents of an archive (not to mention having to reformat the
output of such a listing). Wouldn't be so hard but might cause
problems if people use nonstandard tools.
