VPK is Valve's file format for storing game assets. Pythonic access to VPK files and their contents together with a cli tool.

Works on: python2.7, python3.4+, pypy, and pypy3

Install

You can grab the latest release from https://pypi.python.org/pypi/vpk or via pip

pip install vpk

Quick start

The VPK instance is iterable in the standard ways and produces paths to files

import vpk

pak1 = vpk.open("/d/Steam/steamapps/common/dota 2 beta/dota/pak01_dir.vpk")

for filepath in pak1:
    print filepath

Reading a specifc file is done by passing the file path to get_file() method, which returns a VPKFile instance, which acts as a regular file instance. Writting is not possible.

pakfile = pak1.get_file("scripts/emoticons.txt")
pakfile = pak1["scripts/emoticons.txt"]
print pakfile.read().decode('utf-16le')

-------------------------------------------------
"emoticons"
{
    // An ID of zero is invalid

    "1"
    {
        "image_name" "wink.png"
        "ms_per_frame" "100"
...

Saving a file is just as easy.

pakfile.save("./emoticons.txt")

The module supports creating basic VPKs. Multi archive paks are not yet supported.

newpak = vpk.new("./some/directory")
newpak.save("file.vpk")

pak = newpak.save_and_open("file.vpk")

CLI tool

A command line utility is also included

usage: vpk [-h] [--version] [-l] [-la] [-x OUT_LOCATION] [-nd] [-t] [-c DIR]
           [-p] [-f WILDCARD | -re REGEX | -name WILDCARD] [-v]
           file

optional arguments:
  -h, --help            show this help message and exit
  --version             show program's version number and exit

  file                  Input VPK file
  -l, --list            List file paths
  -la                   List file paths, crc, size
  -x OUT_LOCATION, --extract OUT_LOCATION
                        Extract files to directory
  -nd, --no-directories
                        Don't create directries during extraction
  -t, --test            Verify contents
  -c DIR, --create DIR  Create VPK file from directory
  -p, --pipe            Write file contents to stdout
