DZ extension is not a very popular file extension, it's usually used to compress a dictionary file (hence the name, Dictionary Zip).
Today I got one file of this type and wondered how to extract the dictionary inside. Default file extractor on my Ubuntu machine could recognize the content of the file, but apparently it failed to extract the dictionary. After a moment of googling, I found a way on how to extract a file from a DZ file:
dictzip –decompress dictionary.dict.dz
And the dictionary inside the DZ will be extracted without leaving the original DZ file.
