CDR (Corel Draw Vector drawing file)

Corel Corporation images file

Description: In its first versions, the CDR file format was a completely proprietary file format primarily used for vector graphic drawings and developed by Corel Corporation, recognizable by the first two bytes of the file being "WL". Starting with Corel Draw 3, the file format changed to a Resource Interchange File Format (RIFF) envelope, recognizable by the first four bytes of the file being "RIFF", and a "CDR*vrsn" in bytes 9 to 15, with the asterisk "*" being in early versions just a blank, and beginning with Corel Draw 4, the version number of the writing program in hexadecimal ("4" meaning version 4, "D" meaning version 14). The actual data chunk of the RIFF remains a Corel proprietary format.
