Extract, inspect and rebuild .mpk archives of Where Winds Meet (Everstone Studio / NetEase) — including the current patched game files that older tools can no longer open.
One portable Windows executable. Graphical interface and command line. Nothing to install.
The game changed how its archives are indexed and started scrambling file paths on purpose, so old MPK extractors now output garbage or fail outright. This tool reads the current format, recovers the real file names and folder structure, and can pack everything back into a working archive for modding and localization work.

- Opens current-gen archives — both base-game files and post-update patches (
LT*.mpk,Resources.mpk). - Opens patch containers too —
Patch##.mpkfiles ship no index at all; Probe and Carve modes handle those (see Which archives need which mode). - Real file names, real folders — reconstructs the original directory tree instead of dumping numbered
.binfiles. - Correct extensions — identifies content by looking inside each file (audio, banks, textures, fonts, videos, archives…), so you get
.lua,.wem,.bnk,.png,.dds,.ttf,.oggand so on instead of unknown blobs. - Audio scanner — walks the whole archive and reports which audio streams are actually inside, and how many.
- Integrity checker — confirms in one click that the files it extracted are structurally valid, so you know nothing was corrupted.
- Rebuilder — packs an edited folder back into a working
.mpk+ index pair, including files you added. - Patch database viewer — reads
Patch.mpkdband cross-references it with an archive index, so you can see which assets a specific update touched. - Reports — writes a machine-readable manifest plus a simple one-line-per-file text list you can open in Excel.
- Works without the archive too — if you only have the index file, it opens in a read-only mode and tells you exactly what is missing.
Measured on LT11.mpk from the current version (13.4 MB archive, 3,568 indexed files):
extracted 3,586 files (3,568 indexed + 18 leftover blocks) in ~13 seconds
byte-for-byte verify 3,586 compared, 0 differences
rebuild round trip rebuilt archive is identical to the original, byte for byte
file names recovered 3,208 fully confirmed (90%), the rest with visible gaps
integrity check 3,568 / 3,568 files structurally valid
audio found 0 - correct, this archive holds scripts only
No data is lost and nothing is guessed: whatever the tool writes back is checked against the original before packing.

Windows SmartScreen may warn about an unsigned download — the file simply isn't code-signed. Check the file size and version in its properties, and run it in a sandbox first if you prefer.
Double-click wwm-mpk-tool.exe. Three ways to load an archive:
- Drag & drop a
.mpk(or.mpkinfo) file straight onto the exe icon. - Type or paste the path into the MPK box and press Enter.
- Click Open… (or press Ctrl+O).
The matching .mpkinfo index must be in the same folder as the .mpk — except for patch archives, which have none; use Probe / Carve for those.
| Button | What it does |
|---|---|
| Extract ALL | unpacks everything, keeping the game's folder structure |
| Extract selection | unpacks only the highlighted rows (Ctrl / Shift for multi-select) |
| Rebuild archive | packs the output folder back into a working archive |
| Scan for audio | reports every audio stream actually present in the file |
| Check Lua integrity | confirms the script files were extracted correctly |
| Open Patch.mpkdb | loads the patch database and cross-references it with the open archive |
| Probe / Carve (no index) | opens archives that ship without an index (patch files): diagnose first, then extract what is inside |
| About / Info | version, author, contact links and a summary of what the tool supports |
The table shows each file's name, type, detected extension, size, location and whether its name was fully confirmed. Use the Filter box to narrow by name, content type or category, and tick show un-indexed blocks to also list leftover data the game no longer references.

| Archive | Has an index? | How to open it |
|---|---|---|
LT##.mpk (script / logic patches) |
yes — LT##.mpkinfo beside it |
normal Open / extract |
Resources.mpk and other asset archives |
yes — a .mpkinfo beside it |
normal Open / extract |
Patch##.mpk in LocalData\Patch\ |
no .mpkinfo at all |
use Probe / Carve (no index) |
Patch.mpkdb |
it is the database | Open Patch.mpkdb or the db command |
A patch archive is a delta container: the game resolves its contents through the patch database, so it never ships a per-file .mpkinfo. Opening one the normal way gives "No .mpkinfo index found next to…" — that message is correct, and this is the way through:
wwm-mpk-tool.exe probe G:\Games\WWM\LocalData\Patch\Patch10.mpk
wwm-mpk-tool.exe carve G:\Games\WWM\LocalData\Patch\Patch10.mpk -o patch10_outWhat probe tells you: file size, first/last bytes, whether a side or embedded index exists, how many real content blocks the scanner finds, what percentage of the file they cover, and a breakdown of content types (scripts / audio / textures / unknown). If a file is not a .mpk at all, probe says so instead of pretending.
What carve gives you: every content block it can find, unpacked with the right extension and — where the data carries its own path — the real file name and folder tree. Verified against a fully indexed archive: 3,586 blocks found, 3,586 files written, 100% of the file covered, every payload byte-identical to the index-based extraction.
Honest limit of carve: it works without the index, so it cannot know the game's own file IDs — which means it can extract but not rebuild. Anything it names carve_… had no readable internal path.
# 1. unpack - keep the folder, the manifest inside it is needed later
wwm-mpk-tool.exe extract LT11.mpk -o mymod --orphans
# 2. edit files in place, replace them, or drop new ones into the folder
# (do not rename or move the existing ones)
# 3. repack
wwm-mpk-tool.exe rebuild LT11.mpk mymod -n MODDED.mpkThe rebuild step regenerates the index automatically, reports how many files changed, and creates a matching index file next to the new archive. New files added to the folder are packed as extra entries.
They are compiled game scripts, not plain text — that is normal and expected.
- They will look like nonsense in Notepad. That is true of every compiled script in this game, not a problem with the extraction.
- They are not encrypted and not compressed. Nothing was lost while unpacking: the tool verifies each file and can reproduce the original archive byte for byte.
- To read or edit the logic you need a Lua 5.4 decompiler. Be aware that this game's compiler writes a slightly non-standard header, so some off-the-shelf decompilers complain before they even start.
- If you just want to know whether extraction went well, run Check Lua integrity — it tells you how many files are structurally valid.
Music and voice are not inside the script archives (LT*.mpk). They live in the asset containers — Resources.mpk and the asset patch archives.
Use Scan for audio on a file to see immediately whether it contains audio, and how many streams. On a script archive it will honestly report no audio data here instead of inventing hits.
I get "No .mpkinfo index found next to Patch10.mpk".
That is expected: patch archives do not ship an index at all. Use Probe / Carve (no index) in the window, or probe followed by carve on the command line. See Which archives need which mode.
The tool says the container is missing.
You opened an index without its archive. Put the matching .mpk next to the .mpkinfo and press Reload — or continue in read-only mode to just browse the file list.
Some names contain ~.
The game itself damages parts of its stored paths. Every unrecoverable character is marked with ~ instead of being silently guessed or dropped.
What is an "un-indexed block"?
Leftover data still physically inside the archive but no longer listed by the index — usually an older version of a file. Extract them with show un-indexed blocks / --orphans.
Does it upload or touch anything online?
No. It is offline, reads files you point it at, and writes only where you tell it to.
Will it break my game files?
It never modifies the archive you open; rebuilding always writes new files. Still keep a backup copy of anything you plan to replace in the game folder.
This is a binary-only release. The executable is the product: it is self-contained, needs no runtime and works on a clean Windows 10/11 x64 install.
The internal format research behind it — how the archives are indexed, how names are stored and repaired — is deliberately not documented here. That knowledge is the point of the project, and publishing it would only make it easy to rehost the tool under someone else's name.
- Bug reports, feature requests and "can you support archive X" → Telegram: @Amin_o0x (fastest) or open an issue here.
- Source is not published. If you have a legitimate need for it (integration, audit, learning), ask on Telegram first rather than opening a request here.
- The tool is free to use, redistribute as the unmodified executable, and credit where it helps.
- Probe mode — diagnose any archive without needing its index: layout summary, whether a side or embedded index exists, how many real content blocks are present, what share of the file they cover, and a breakdown of content types
- Carve mode — extract those blocks anyway, with correct extensions and real paths where the data carries them. This is the answer for
Patch##.mpkfiles inLocalData\Patch\, which ship no index and previously could not be opened - Both are available on the CLI (
probe/carve) and in the window as Probe / Carve (no index) - Fixed: carving no longer overwrites a file when two blocks share the same path — duplicates are suffixed instead of silently lost
- Fixed: the "no index found" message now explains which archives have no index and what to do instead
- Smarter name recovery from an extra length marker the game stores per file
- Native compiled build: smaller download (8.99 MB, was 12.9 MB) and no Python bytecode shipped
- Supports the current (post-update) archive and index format
- Real file and folder names recovered, with per-file confidence marking
- Content detection by inspecting each file, so extensions are correct
- Audio scanner that reports only genuinely present streams
- Integrity checker for extracted scripts
- Rebuilder with automatic index regeneration and change reporting
- Patch-database viewer with cross-referencing against any archive index
- Read-only mode when only an index file is available
- Crash fixes: loading an archive, rapid button spam, closing the window during a scan, and clean one-line messages instead of raw tracebacks
- Drag & drop, Enter-to-load, Ctrl+O
- About window with version and contact links; the same information is embedded in the exe's file properties
- Byte-exact round trip verified (extract → rebuild produces a file identical to the original)
- Application icon and Windows file properties
