That 3d file manager was called 'fsn'. Then there is a gtk/Linux port called 'fsv'. I maintain a version updated to gtk+3 at https://github.com/jabl/fsv . Unfortunately life has gotten in the way and I haven't had the time to port to gtk4 nor add some missing features.

When that movie came out, I was in school and living in special interest housing for computer science students. A bunch of us went to see the movie together, and when she said that line we all erupted in laughter, much to the confusion of the rest of the theater.

I am getting old. That reference is from 1993.

I will not spoil it but for those not in the know: https://imdb.com/title/tt0107290/

FWIW i haven't seen that movie but i've heard this reference A LOT :-P
