Any chance the images once lived in CONTENTdm? The application assigns internal file names to uploaded digital objects with the file extension .cpd.

Subject: [CODE4LIB] .cpd file format head scratcher
For a set of digitized pharmaceutical cards, I am coming up against an image file format that seems to be locked in time. It's supposedly a Compressed PhotoDefiner (?) lossless (.cpd) file (http://www.photodefiner.com/home/). Though when I try to load up the software, I can't get it to take on any of our windows machines (running 8 and 7). Don't have a mac on hand so don't know if that works or not, currently.
In my experience, though, I've always been able to find some rogue third party file converter (or imagemagick) to be helpful in these scenarios but this format is just not something that appears to have been accounted for. Additionally, it's one of those file formats that seem to only pop randomly generated answer sites with questionable downloads in a google search, such as http://www.solvusoft.com/en/file-extensions/file-extension-cpd/
Just wanted to see if anyone has come across this format and whether there might be any tools to convert it.
