Very informative read overall.

all files are either text, binary blobs or archives (zip), no exception
I personally knew about this when I needed to extract all images from a Word document in 2015, I had the idea to rename the extension to .zip and wow a conveniently placed media folder !
since then I renamed countless file extensions to zip, just to test. it worked nearly every single time

Hah! That's also how I first learned about the zip trick with pptx.
Had never considered it generalizes outside of OOXML files. I'll give it a try next time I'm poking around another file format

i've been struggling a lot with my team to standardize our presentation systems. as soon as we got claude people just started making adhoc, non-standard, slides. This is good because they're 10x better than the bullshit one offs PMs used to make. But as a result we've got 80 different ways of conveying the same type of information to our leadership. And its pissing those leaders off.
Getting people aligned on a single template is our biggest headache for the ops side of the house. Will definitely need to research this further. Thanks for the post.

I knew a powerpoint is basically a zip file when I was trying to crack a pptx file last year, the AI basically said “pptx file is basically a zip file, let’s do …”, when I unzipped it, turned out the password protection is useless, all assets and everything are in there unprotected, including the 3D models inside. And you can pack it to a file again, just like the protected one but with no password.
