You can't get a citation for this, and I must admit that this was a bit of a hyperbole. Still, I sincerely believe that in a typical year, a typical user runs into zero or one .zip files. Of course there are exceptions, but these power users do not make up a large part of the population. Facebook and Instagram are not shipped in .zip format for a reason. Here are some numbers to think about: According to Microsoft, there are ~1.4 billion devices that run Windows 10 or Windows 11 [1]. Apparently, there are some 200 million additional devices that run older versions of Windows [2]. Now, I could hypothetically ask my mom and dad, and find out that only one of them knows what a .zip file is. The other has not heard of .rar. I don't think I myself am a typical user, but I do know .rar, and I do not even have WinRAR installed. That leaves me to conclude that it is very, very, unlikely that 31% of all Windows users has WinRAR installed.
