VDK file structure (Ragnarok Online, Requiem)

The structure of VDK files which are used in Ragnarok Online 2 and Requiem

Code:

---

//--------------------------------------
//--- 010 Editor v3.1.2 Binary Template
//
// File: vdk 1.1
// Author: Dwar
// Revision: 2010-09-05
// Purpose: vdk unpacker
//--------------------------------------

//vdk header
struct VDKHeader                   
{
  char VDK_desk[8];    //VDISK1.1
  int  VDK_unk;        //unknown
  int  VDK_CountFile;  //file count
  int  VDK_CountFolder; //folder count
  int  VDK_size;        //vdk file size without root (+91h) and FileList
  int  VDK_unk;        //unknown
} Header;

// read files data until VDK_size + 91h
struct Files                   
{
  byte isDir;
  char fileName[128];
  int  SizeOriginal;
  int  SizePacked;
  int  parentDirOffset <format=hex>;
  int  NextAddrOffset  <format=hex>;
};

//
struct FileList        // list of files at the end                 
{
  int  VDK_filecount;  //file count
  char fileName[260];
  int  fileOffset <format=hex>;
};

Can you please explain what you mean by <format=hex> (as for parent directory offset and next address offset)? If the values are save as an int wouldn't you just use the raw value when parsing the vdk?

Is this the updated version for Ragnarok Online 2?

hi can i know wat tools using to edit the file
can teach me how to edit ..thx
