What is floopy?

I assume you mean "floppy disk". A floppy disk is a type of magnetic storage medium that was widely used in computing from the 1970s through the early 2000s. The most common size was the 3.5-inch disk, which could hold up to 1.44 megabytes of data. Floppy disks were fragile and prone to corruption and data loss, and they were eventually replaced by more durable and capacious storage options like the CD, DVD, and USB flash drive.
