I just looked up how KDE does it, in case you're using that, the file manager is called Dolphin, and apparently you might need to install an archive tool first such as Ark and/or 7zip, gotta give you that one, I'm a little shocked, that's a pretty shitty OOBE in my opinion[..]

I think that's an artifact from running just the liveimage and not installing it fully to the VM. I'm 99% certain Ark is included in a default Cachy/KDE install.

It is, even if not impossible, entirely impracticable to prove any work is AI free. So no one but you can be sure.
