In nearly every icon set that bothers to draw it, the command to save your work is still a floppy disk, a small square with a sliding shutter and a paper label, faithfully rendered decades after the last drive that could read one went dark. The hardware is long dead. The picture of it lives on, clicked millions of times a day by people preserving documents to storage that bears no resemblance to a magnetic diskette. This is skeuomorphism outliving its source, a symbol that has quietly cut loose from the object it once depicted.

The remarkable part is that the meaning survived the thing. A whole generation has now grown up having never held a floppy disk, never felt its cheap plastic heft or heard the drive grind, and yet they read the icon without a moment's confusion. Tap the little square and your work is safe. The image no longer points at a real object in the world; it points only at an action, which is as pure a symbol as an interface can produce. The disk became a hieroglyph for saving, its literal meaning fossilized and forgotten. Icon libraries handle this legacy in revealing ways.

Tabler is straightforward about what it is drawing, naming its glyph device-floppy, calling the object by its name even as the object vanishes. Heroicons, alone among the major sets, refuses the floppy altogether. Rather than perpetuate a picture of dead hardware, it offers an arrow tucking down into a document, an attempt to show the act of saving directly rather than through a relic. It is a small act of dissent in a field that has otherwise agreed to keep drawing a machine no one uses. The floppy persists anyway, the most durable ghost in the icon tray.
