I'm just guessing here, but if I recall correctly, android was started as an OS for digital cameras. So saving camera files to DCIM (Digital Camera Images) makes sense as that is standard to most other cameras

I'm in that group I think. I do like a liiitle bit of coding in some tiny specific progrqmming language in one piece of software that I use. I understand the basics but try to avoid having to do it. But while code is a little scary to me, math is much scarier lol
