These two scripts will allow you to extract both KDZ files and DZ files

Run unkdz.py or undz.py with the -h option to get more options.

    -l or --list  
            Lists all files contained in the archive  

    -x or --extract  
            Extract all files in the archive  

    -s ID or --single ID  
            Extract a single partition by ID (can be found with --list)  

    -o DIR or --out DIR  
            Set output directory instead of the default "[kdz|dz]extracted" directory  
            in the current path  

    -f FILE or --file FILE  
            Input file to operate on  

A simple method to extract a KDZ file is as follows:

python KDZFileTools.py -f LAS_V08d_pre3_00.kdz -x

[+] KDZ Partition List

0 : LAS_V08d_pre3_00.dz (1428092632 bytes)
1 : LGUP_8974.dll (1477632 bytes)

python KDZFileTools.py -f LAS_V08d_pre3_00.kdz -s 0

[+] Extracting single partition!

[+] Extracting LAS_V08d_pre3_00.dz to kdzextracted/LAS_V08d_pre3_00.dz

python DZFileTools.py -f kdzextracted/LAS_V08d_pre3_00.dz -l

From here, you can simply run the following command to extract a specific partition, or use -x to extract all:

python DZFileTools.py -f kdzextracted/LAS_V08d_pre3_00.dz -s 4
