Someone like my mom, she knows Spreadsheets as green files, and other than the color and that they open Excel, for her they're the same as any other file (Windows default hiding extensions doesn't help either)

Recently, she asked me to put a set of documents into a folder (She meant a compressed file) because some page required it

I have always found it fascinating, considering she has worked with Office products for the last ~20 years

It's wild to me some of the things I never knew, even though I've been using Windows or DOS for probably 35 years.

For example, I recently learned you can't name a file CON. Try it. Somehow over all those decades, I've never tried to do this until Tom Scott made a video about it:
