Some format lists report a "CPX"/.cpx format named "Corel Presentation Exchange compressed" or "CMX compressed" (e.g. x-fmt/36), but I'm having trouble confirming that such a thing exists. If so, how does it relate to CCX?

There is definitely a Corel CPX format, used by Corel ArtShow 5. But is "Corel Presentation Exchange compressed" is a suitable description of it? -Jsummers (talk) 16:03, 11 December 2019 (UTC)

I have been looking for samples of CPX and CDX (x-fmt/31), both compressed versions of Corel formats to no avail. I am seriously doubting their existence. I went back to every CorelDRAW version and found the earliest one that have it listed in the filters.ini and found they are import only. Where they com from I have no idea. The earliest Clip Art sets I can find don't use the compressed formats either. Still a mystery. --Thorsted (talk) 16:20, 11 December 2019 (UTC)
