CDR means compact disc-recordable. Like most compact discs, CDRs can only store somewhere between 700-800MB of data. The unique thing about them is that they can only be used for recording once. After that, it is a read-only disc. As such, whatever you will record on a CDR will remain unchanged forever.
Ensure that your setup is capable of working with rewritable CDs. To erase files from a CD-RW, you will need both the rewritable disc itself and an optical drive capable of reading and writing to CD-RWs. This capability will be listed on the front panel of your optical drive.
