No. After a CD or CD-R is created, it cannot be edited, erased, formatted, or otherwise modified. If you’ve created the CD or CD-R and want to modify it, recreate it using a new CD-R.

If you’re using a CD-RW disc, it can be modified. Information written to the disc is linear, which means if a disc file is modified, it must be re-written to the disc. The existing file on the disc cannot be modified.

Before you continue, make sure you have another blank CD-R, so you can create the new disk.
