There's a lot of information crammed onto this Elephant Computer Systems floppy disk, and I don't mean the digital data. It's overflowing with external, physical clues and markings that show how it has been handled and used over its lifespan. Archivists call this "metadata" — that is, data about the data — and it is often lost when things are digitized.
The most obvious pieces of metadata from the labeling on the disk are about who manufactured it ("Elephant Computer Systems"), its optimal capacity ("single-sided, single-density") and intended usage ("soft sector"). If you familiarized yourself with the technical specs of the floppy drives of computers available in the 5.25″ floppy era, you could rule out a few systems. That could be useful if other platform-betraying clues were absent on the disk.
Another obvious set of metadata comes from the presumed contents of the disk, which we can infer from the printed file directories taped to the disk jacket. Again, if one were familiar with the program names in the listing, one could point to a specific computer platform. (In this case, the printout looks like a DOS 3.3 "CATALOG" listing from the Apple II.)
Let's take a step deeper into the less obvious metadata presented to us by this artifact. From visually inspecting the disk, we can tell (among other things):
