Use the find function in your editor, don't just scroll. Well, they zip at about 4 to 1, so a 1.6 mb file is 330K. The obj file only compress about 3.5 to 1, so they are maybe 450K. They fit on my floppies. In order to get a lot of compression you would have to go to a binary format. That would intoduce a whole lot of problems. It's like dealing with a corrupted registry file vs a corrupted .ini file. If you corrupt your registry you get to reinstall windows, and all your applications. That is the MS improvement over having to edit those nasty text ini files, which NOBODY could manage. It is so much more efficient to throw away a day or two reinstalling windows and 20 applications than to spend ten minutes editing a somewhat cryptic file. Not that I should complain, since this improvement by MS has really done great things for my standard of living, but still, I like text formated files. They might introduce the ability to dynamically zip and unzip files, which would be fairly painless, but I would be strongly opposed to going to something that results in a binary fomat that will be totally impossible to edit. Notice that Meta has put out ZERO documentation on poser internals. So if we can't explore it we can't work with it except directly through poser. And since you are obviously finding it necessary to directly edit the CR2 you have begun to see the limits that this may cause.
