Back then it felt like half of users swore by Norton commander and had to organize files every day for some reason.
The other half just didn’t bother.
My observation is that one of these groups later used Winamp and managed their own music files in some elaborate structure and the other group found that iTunes kept a structure (not perfect, but with zero effort) and loved it.
(There are lots of overlaps here e.g I guess which group is now on iOS and which felt “I’m using Android because it’ll let me manage my own files”?)
My first reaction was "very busy design" which is not bad (think about Excel) but those overlapping folder names are puzzling. Maybe they are OK when one is familiar with a file system layout, which is the case for all of us on our own computer. Same thing for all the other panes. It could be one of those tools for power users that need a complex UI because they do complex things.
