Put the Floppy disk in, and run the command:
The contents of your floppy disk should now appear under /media/floppy.
Copy whatever files you want to the floppy, and then run:
Make sure that your current directory is not under /media/floppy when you do this, and make sure you run the command before ejecting the floppy. If you don't your files will not be copyed.
I hope this helps
