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.
Oh man the masters and layout proliferation is the biggest pain.
If you can, I'd do a bare bones starting template with like Cover, section divider, and title only layouts. Lock in slide dimensions, fonts, colors. Then ask (and pray) people upload that instead of letting Claude work from scratch.
Even if everyone goes in a different direction, it's much easier to merge and conform styles if you're working on the same template with minimal placeholders.
Ideally you get a library of "best practice" slides that people use as a starting point, but realistically people love doing their thing. Key is to set yourself up for an easy cleanup.
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.

Very informative read overall.
Thanks! Glad it was useful.
