I remember installing software from multiple 5.25 disks, then later from multiple (many many multiple) 3.5 disks. I forget how many disks windows 95 was, but I remember it being a lot. Then zip disks and the click of death. Fun times there.
I kind of wish I had kept some old disks, just to show my grandkids someday. But at the same time, I'm glad we're past that technology. USB thumbdrives are so much more convenient.
