That 3D file system browser (I presume you’re talking about Jurassic Park) was totally real.
It was a tech demo that SGI included with IRIX called “fsn”. Ironically, at the time, many people criticised it for being unrealistic. There is an open source clone called “fsv”.
Either Slackware or Red Hat Linux 5, can’t remember. I do remember that when I first installed RH5 I used “Hick” for my language.
