As I don't have a physical device for my floppy image (see #14), I've created a /dev/loop0 device with a command

sudo losetup /dev/loop1 ./floppy.img

However, when I try to use a command like

sudo fatresize -s 2880k /dev/loop1

I get this output:

fatresize 1.0.3 (03/05/20)
You must specify exactly one existing device.

Perhaps this has to do with /dev/loop1 device having one more letter than i.e. /dev/sdd1

I'm going to add a logic to handle loop-devices as well. Thank you for reporting.
