## pzztool.py
Python3 script for unpack/repack and uncompress/compress of PZZ archive.

### User manual
Unpack **source.pzz** in the default new folder _source_. If optional_dest_folder is specified we unpack in _optional_dest_folder_.
```
pzztool.py -u source.pzz optional_dest_folder
```
Pack **source_folder** in the default new pzz file _source_folder.pzz_. If optional_dest.pzz is specified we pack in _optional_dest.pzz_.
```
pzztool.py -p source_folder optional_dest.pzz
```
Unpack every pzz files present in _source_folder_ using the same directory. For each pzz a folder is created using the name of the pzz. If optional_dest_folder is specified we unpack all files in _optional_dest_folder_ instead of source_folder.
```
pzztool.py -bu source_folder optional_dest_folder
```
Pack every folder present in _source_folder_ using the same directory. For each folder a pzz file is created using the name of the pzz. If optional_dest_folder is specified we pack all folders in _optional_dest_folder_ instead of source_folder.
```
pzztool.py -bp source_folder optional_dest_folder
```

### Extracted files format
Every file extracted has a name using the format :

AAAB_C.D
- **AAA** is the 3 digits index of the file in the PZZ starting at 000.
- **B** describe the compression state of the file when packed in the PZZ. If compressed it's **C** and if not it's **U**.
- **C** is the name of the PZZ.
- **D** is the extension of the file. If the file is compressed it's **.pzzp** and if the file is uncompressed by default it's **.dat**

For example file **012C_cmn_data.dat** describe :
- the 13th file off the pzz,
- initialy compressed,
- in a pzz named "cmn_data.pzz",
- that has been uncompressed,
- with the default format "dat".

The names of unpacked files and the presence of empty unpacked files are important to keep informations relative to the initial pzz and ensure a correct pack.
