The system of disks and floppies in ComputerCraft is very similar to how they would work in the real world with our real computers: There's a Disk Drive that we're able to insert removable disks (or floppies) which we're able to place data upon, which, in turn, makes data portable. This brings much potential for things such as servers running ComputerCraft and users of that server wishing to distribute their software for in-game currency.
The 1.42 update allows floppies to be colored with any kind of dye. This is done by putting a floppy and a dye in your crafting table.

Like individual computers, each floppy disk has its own folder containing the data that is within that floppy and is easily movable from within the computers in Minecraft using the simple UNIX-like commands such as cp (copy) or mv (move). Just like anywhere else in a computer, you can create, edit, move, copy, etc., any files and do so however you wish.
To insert a floppy into a Disk Drive so it can be used, right-click the disk drive and place the floppy into the slot at the top of the drive's inventory menu.
Interacting with Computers Edit
When a disk is inserted into a disk drive that is adjacent to a computer, a directory is visible in the computer's root directory titled 'disk'. If another disk is inserted into a different drive that is also connected to a computer then that next directory is entitled 'disk2' and so-on for each additional disk that is inserted and connected.
