Floppies are a type of disk storage device that was popular in the 1980s and 1990s. They are also known as floppy disks, or simply floppies. Floppies are thin, circular disks made of flexible plastic, with a magnetic coating on one side. They were used to store data, such as documents, images, and programs, and could be read by computers. Floppies were eventually replaced by more modern storage devices, such as CDs and USB drives.
