When you look at Windows 95 installation disks, you will notice that the boot disk, as well as the first setup disk are regular sized images. The rest of the images seem to be larger by around 250 kilobytes.
In this video, I will have a look at floppy disks and a different way to format a floppy disk allowing up to 1.72 MB of space.
