Features

• Merge: Combines extracted folders (re_chunk_000 and re_chunk_000.pak.sub_000) into a single folder.
• Unmerge: Splits a merged folder back into re_chunk_000 and re_chunk_000.pak.sub_000 using .list files.
• Split: Splits a .list file into separate files for re_chunk_000 and re_chunk_000.pak.sub_000.
• Automatic File Download:
  • If RETool.exe or MHWs_STM_Beta.list is missing, the script will automatically download them.

1. Extract .pak Files

1. Drag and drop a .pak file onto extract-wilds-pak.bat.

   • Extract the .pak file using RETool.exe.

2. Merge Folders

Run the following command to merge folders:

MHWs-Ext-Manager.exe merge <source_folder> <destination_folder>

Example:

MHWs-Ext-Manager.exe merge re_chunk_000.pak.sub_000 re_chunk_000

---

3. Unmerge Folders

Run the following command to split a merged folder back into two separate folders:

MHWs-Ext-Manager.exe unmerge <merged_folder> <list_file_for_re_chunk> <list_file_for_sub_chunk>

Example:

MHWs-Ext-Manager.exe unmerge re_chunk_000(merged) re_chunk_000.list re_chunk_000.pak.sub_000.list

---

4. Split .list File

Run the following command to split a .list file:

MHWs-Ext-Manager.exe split <input_list_file>

Example:

MHWs-Ext-Manager.exe split MHWs_STM_Beta.list

Important:

• Before using the split function, ensure that re_chunk_000.pak and re_chunk_000.pak.sub_000.pak have been extracted into their respective directories (re_chunk_000 and re_chunk_000.pak.sub_000).
• The split function will compare the list entries with the extracted directories to generate accurate output files:
  • re_chunk_000.list
  • re_chunk_000.pak.sub_000.list

---

Notes

• If RETool.exe or MHWs_STM_Beta.list is missing, the batch script will automatically download them:
  • RETool.exe will be downloaded from RETool GitHub Repository.
  • MHWs_STM_Beta.list will be downloaded from Ekey's GitHub Repository.
• Ensure that RETool.exe and MHWs_STM_Beta.list are located in the same directory as the batch script after the first run.
• The tool is optimized for Monster Hunter Wilds .pak files but may work with similar formats.
