Like when you send a .7z instead of a .zip or .rar to a friend or a teacher because that’s what your computer has installed and they’re like “Oh No, not one of those, now I have to install 7Zip” even though the same program that opens .rar also opens .7z I feel like people are way more annoyed when they receive a .7z
I would imagine downloaded exe files are also blocked.
Good point. There are ways around it, but only tech savvy people are going to do those, so probably best to just use zip.
USBs?
