The webpage provides information about the file so it’s clear what it is at the instant that you download it. The problem is more that a week later when you look at your Downloads folder, you will have no idea what “GenericDriverSetup.exe” is. Is it video card drivers? Drivers for a modem from a different vendor? etc.
Or maybe you need to install on a new computer and you’re wondering if you have the latest version of the driver. It’s difficult to know because the filename doesn’t indicate the version.
