Do CDRW's need to be formatted before using?

[MustISO]

If so, what program is used to format them? I have directCD but I thought that format was only so that you could use the drag and drop burning feature.

Thanks

You only need to do the formatting if you want to use it like a floppy.

You don't need to format it if you use it like a standard CDR, and then erase at the end.

also remember that if you format the cdrw then you'll end up with around 550Mb of space vs 650Mb if left unformatted!
