Cool Reader dictionary

[mszef]

Hello
I'm trying to add my dictionaries for Cool Reader on Pocketbook 626.
I've created folder in share/cr3 called dict
and I've copied there all my ColorDict dictionaries that worked well on old NOOK cool reader.
However when I try to use my dictionaries I have error opening dictionary.

I've copied all files to the same folder. It is 6 different dictionaries with multiple files (cdi, dict, idx, ifo). One dictionary doesn't have ifo file.

I couldn't find any additional info on wiki page.

Thanks for help.
