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. Released as compressed formats on the Corel ArtShow CD's during the 1990's[1].
