CorelDRAW CDR Signature Format: Introduction & Recovery
CDR file format was developed by Corel Co. in 1989, and it was an entirely proprietary Corel file format. It was mainly used for vector graphic drawings, and it could be recognized by the "WL", the first two starting bytes of the file. With CorelDRAW 3, CDR has changed its format and its name to a Resource Interchange File Format (RIFF) envelope. The new format could have been recognized by the four starting bytes ("RIFF") of the file, and by the "CDR*vrsn" in bytes 9 to 15. Corel continues to be the proprietary owner of the data chunk of the RIFF file format.
