CD-RW is a reusable disk. You can add files all at once and delete all files all at once. But you can't rearrange, rename or delete individual files on the disk. To make any changes, you would have to copy the files to your computer, make the desired changes, erase the CD-RW, and then copy them back to it.
Think I did a bad thing. Bought a box of Samsung CDRW 10X...and copied files to the CD and tried to rename and delete the files--message popped up "read only" ....Okay...is there an eraseable CDRW? What should I buy if I want to delete & rename files. Thanks.
