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
Why the fuck would you purposely piss of a teacher who has control over your future, and who probably doesn’t even have admin access to install apps. You sound like a basement dwelling incel.
