I feel like you're not getting the point. Let me clear it out again: I'm not against it. Do whatever the hell makes you happy.
There's no need to archieve any sorts of software for current machines unless it's cruical or somehow important to you. I'm not saying you can't; you just don't need to. That's what I meant all from my first reply. I don't get why you're so much overreacting like it's a life or death situation.
All of the important software you'll need today are already arcieved or have thousands of alternatives for you to use. Unless you're not using an extremely outdated machine which will need specific software, which, again, you can find the needed software on the internet effortlessly, which means you don't have to do it.
We're not living in the 20th century anymore. Archieve whatever the hell you want, wheter it's furry porn from 90s or a very specific audio card driver that no one ever heard about, I'm fine with it.
