There is a link to the folder - to avoid repetitions:
In the Russian mirror you have to open the .md file to see it. Besides, I don’t speak Chinese/Cantonese and I don’t know what is what and where to distribute it.
There is no official folder of dictionaries on freemdict cloud. They are all uploaded and maintained by warm, kind and helpful guys, like you and @Wankata , etc.
Correct, those Cantonese files are not in the folder maintained by @Wankata , but in FreeMdict Cloud.
