Padding for a Floppy is even easier than for a HardDisk - all we need to know is the desired final size.

; This file performs the necessary padding to generate a .flp or .img file.
; All of the hard work has been done: all we need to do is generate
; sufficient extra bytes to make the resultant output file large enough to
; satisfy programs like earlier versions VMware.
; These programs use the file size to determine the size of the simulated floppy,
; and from there the geometry to use (number of sectors per track, number of
; tracks per side, etc.)
