Formatting CD doesn't delete files?

I have a 700 meg CD-R disc with some files on it. I think I originally
formatted it as Mastered. I wanted to wipe out all files quickly so I
formatted it -- File System: UDF 2.01, Allocation unit size: 2048 bytes.
But afterwards, looking at in Properties, I see that there's still 200 megs
used space. And putting it in the CD drive in my old Win2k machine, I still
see all the files that I thought I'd wiped out! What am I doing wrong?
Thanks.

It might be that you need a CD-RW disk.
Once a CD-R disk is written, you can only read it.

Thanks. Not even re-formatting will wipe out its files?

No... but breaking it in half will do the trick.
