Joke? Use l2disasm or another...
The soft reads decoded files, so it saves decoded files. If you want to use them in the game, they must be encoded ...
FileEdit opens the file only if they are encoded.
Sorry but I don't understand why you want path the files from parser.
Patcher.exe is just a shorthand to create a dat files list and run the command "l2encdec.exe-s" on this list and backup the original file. Only used on original files from ncsoft.
