RAW is probably just a simple lossless compression. If pixels (1254,358) through (1260, 358) are all black than it can just put that down. Same thign as JPG but it just makes it more efficient file savings without losing any information.

Compression software works like that. A picture with little details (for instance with a big blue sky) can be compressed more than a picture with lot of details (for instance trees or grass).

So it's a simple RLE file then? seems unlikely to me that this would generate such wildly varying file sizes that I've, seen, but maybe you're right...there is obviously some kind of comression going on, but I would be surprised if it's RLE only.
That is my understanding too, but the file system is proprietary. Thus we don't know where and how they store the information within the file. I can't imagine that it is exceedingly complex, and I still don't understand why Canon won't share the code with developers?
It is a lossless compression. Canon probably doesn't share the code
because most lossless compression techniques are licensed and covered
by patents. They can't give away what they don't own.
