I have a digital camera that uses floppy disk, how can I reuse that floppy disk that I no longer want?

I have a disk that has pictures on it, that I no longer need. Do I just pitch it or can I reformat it and if so how. Thanks

insert the floppy in the drive.right click on the drive from my computer.click format from the menu.it is ready.

Exactly right. Reformat and the disc is as good as new.
