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’m a Linux user, so I use .gz and .bz primarily for compression. If I just need to archive without compression I’ll just make a tarball. People on windows never complain. Maybe it’s just that I’m in the IT field, but most people have an archiving program installed. Plus, I am pretty sure Win11 can open most archive formats natively now.
