I would like to add something to Chris' comments:
The advantage of the PCM and mesh2 formats over a zipped mesh format is
that the formers can be directly read from the file itself.
In order to read a mesh inside a zip file you would have to first
decompress the zip file. This is even worse than just having the uncompressed
version: You don't only have the uncompressed version of the mesh, but you
also have the zipped version, thus requiring more disk space.
With the PCM/mesh2 format you don't need any extra disk space since you
can directly read the file into povray (with a macro in the first case
and directly in the second case).
The advantage of mesh2 over PCM is that reading a mesh2 is a lot faster
(it's even faster than reading a mesh).
The advantage of the PCM format is that you get extra functionality
(such as those mentioned by Chris).

We have been planning for an extended PCM format which will support
uv-mapping and per-triangle/per-vertex texturing (and even texture definitions
inside the PCM file).
The format is quite finished, but I have been "coding" support for it into
the compressor for the last half year (that is, I haven't done anything ;) ).

My compressor doesn't do this (you'll have to use a SSS variant if you
want that functionality). It just writes a mesh in a more compact format,
that's it. It preserves all the triangles (well, it can remove degenerate
triangles if asked).

I have zip, rar, lha, gzip and bzip2 (and other less known)
compression/decompression and arj decompression software in this machine
(I think they are all generic unix programs).
I think that's mostly enough.
(Btw, bzip2 compresses better in almost every case and faster in most
cases than any of the other compression softwares; I wonder why it isn't
more popular in Windows systems...)

I thought you meant that that could be done with pkzip for windows. Time to go
redownload pkunzip DOS...

no, just plain unzip, for example:
ftp://ftp.info-zip.org/pub/infozip/WIN32/

Tnx, but I've already dl'ed pkzip dos 2.50 and made the batch file and set it to
default action. Too fast for ya. ;)

Well, it is probably slower and cannot handle long filenames...

I'd be very interested in more information about this format.
More specifically the new format definition.

I haven't used pk(un)zip 2.50 in ages, but I seem to remember it did
handle long file names properly.
