Opening .cdt files

In clearing out old storage, I came across several CDs with .cdt files on them - supposedly thousands of  CorelDraw images. I downloaded CorelDraw x7, but get "I/O Read Error" when I try to open the files. The same happens for all cdt files I've been able to locate online to use as tests, also.
 
How the heck does one open these files?

I actually tried that first, but kept getting "UniConvertor failed" errors, so I thought I'd go right to Corel.

It turns out these aren't CorelDraw templates (at least they're not RIFF files, which sources suggest CDTs are, and inkscape/etc won't open them); they're some other form of .cdt file.  
 
Each file is a few thousand length-delimited jpgs concatenated together, I hacked up a little script to explode them out into individual files for Kartvelo.
