The Compact Disc File System (CDFS) is the file formatting system used by optical disc media to designate a compact disc (CD). All CDs, whether audio, video or data, are all formatted in a type of CDFS. If you want to format that file system and remove the data on the disc, you can do so if the disc is a CD-ReWritable (CD-RW). CD-RWs are a special type of compact disc that allow you to write, erase, and rewrite content to them at will. You can format the contents of a CDFS on a CD-RW using Windows.
Insert the disc into your computer.
Click "Start," then "Computer."
Click the disc and then click "Erase this disc" on the toolbar.
Click "Next" to begin erasing the contents on your disc. This will format the entire disc and clear all content.
