CorelDRAW
From Just Solve the File Format Problem
CorelDRAW is a vector graphics drawing program. Its native file format is generally found in .cdr files, but other extensions exist for variants of it. The format has gone through several major revisions over the years.

Format description
Early CorelDraw files are of an undocumented proprietary format where the first two bytes spell WL in ASCII. Later formats were based on RIFF, with RIFF as the first four bytes and a version identifier in bytes 9 to 15. The inner details (the data chunk of the RIFF version) remain proprietary.
Compressed formats, .CPX & .CDX are open/import only filters in versions in CorelDraw from version 6 on. Support for CDX was dropped after X6. Presumably formats released from Corel as clipart. (need to samples to confirm)
