This really bugs me at work sometimes. I'm a designer and I often have to split up images in several mails because others don't understand the concept of archives. Or even worse: send the photos as "excel image file" (slapping them all in a excel sheet). I even once had a printery tell me my file was corrupt because it was (accidentally on my part) compressed as 7z. Oh how I would love to send files more often as 7zip... But that's black magic apparently.
I used to work in a camera shop back in the day. Alot of people came in with a thumb drive of some sorts, and wanted pictures printed of images in a word-document. They were baffeled when we said we can't print it with our lab. "But it is right there on the screen!"
I work in software, and have recently gotten the opportunity to be on the other side of interviews. As part of the interview process, we send out a code challenge (super simple, shouldn't take long at all). One guy sent his solution in in a docx file. God i hope he was trolling.
Side note: chat gpt has ruined take home assignments for interviews.
Well at least windows just treats archives as folders as infæ you can just double click on them. Don't even have to extract anything to work with the files
