The floppy disk drive is a device that records data onto a removable storage disk called a floppy disk. Floppy disks, also called "floppies", were the most basic storage medium for data. However their limited capacity, typically 1.44 megabytes, rendered them obsolete with the developement of writeable CDs and DVDs and USB flash drives. Once found on all PCs, manufacturers no longer include them in new PCs.
A floppy disk was used to copy files from one PC to another PC or for making backup copies of files.
