PakFu

Step into the PakFu dojo: your Sensei demands tidy archives, sharp tools, and workflows you can repeat without hesitation. Respect the palettes, mount containers within containers, and keep your mod workbench disciplined. Train with the GUI for comfort, or the CLI for speed.

PakFu is a cross-platform archive manager and asset viewer for idTech-era and adjacent game formats. It is built with modern C++ and Qt6, and it keeps both GUI and CLI workflows first-class.

Overview

• Current version: 0.1.18.1 (see VERSION).
• Cross-platform targets: Windows, macOS, Linux.
• Build system: Meson + Ninja.
• UI framework: Qt6 Widgets.
• Primary focus: browse, inspect, preview, extract, and rebuild archive content with a documented CLI.
• Project state: active development with frequent feature updates.

Download

Get PakFu from GitHub Releases:

• Windows: installer.msi (recommended) or portable.zip
• macOS: installer.pkg (recommended) or portable.zip
• Linux: installer.AppImage (recommended) or portable.tar.gz

PakFu can also check for updates at runtime (GUI) and via CLI (--check-updates).

Highlights

• Archive and folder support in both GUI and CLI.
• Dedicated standalone viewer windows for image, video, audio, and model files.
• Nested container mounting (open archives inside archives).
• One-click Extract Selected and Extract All workflows for the active archive tab.
• Batch conversion tool for selected assets with category tabs (images, video, archives, models, sound, maps, text, other).
• 3D preview renderer selection with Vulkan/OpenGL behavior and fallback.
• Fly camera controls for 3D preview (Right Mouse + WASD, Q/E, mouse wheel speed, Shift faster, Ctrl slower, F frame, R/Home reset).
• Auto-detection and management of per-game installation profiles.
• Built-in update checks via GitHub Releases.
• Integrated crash reporting with session logs and Windows minidumps.
• File-association management UI with per-format icon sets.

Preview And Inspector Support

• Images:
  • Core: pcx, wal, png, tga, jpg
  • Also supported: jpeg, bmp, gif, tif, tiff, swl, mip, lmp, dds, ftx
• Audio:
  • Core: wav, ogg
  • Also supported: mp3, idwav (Doom 3 BFG; converted to WAV for playback when payload codec is supported)
• Video:
  • Core: cin, roq
  • Also supported: bik, ogv, mp4, mkv, avi, webm
• Models:
  • mdl, md2, md3, mdc, md4, mdr, skb, skd, mdm, glm, iqm, md5mesh, tan, obj, lwo
• idTech inspectors and metadata views:
  • spr, sp2/spr2, dm2, aas, qvm, progs.dat, tag, mdx, mds, skc, ska, ttf, otf
• Text and script assets:
  • Core: cfg and similar plain-text config/script files
  • Includes many common idTech-family script formats (shader, menu, def, mtr, map, ent, qc, and others)

Notes:

• Multimedia playback support depends on the installed Qt Multimedia backend and codecs.
• cin and roq are also handled by built-in cinematic decoders.
• Some indexed formats (wal, mip, selected lmp cases) use game palettes when required.
• BSP inspector/preview supports Quake 3-derived families including FAKK variants used by Heavy Metal: F.A.K.K.2 and American McGee's Alice (FAKK v42 checksum-header BSPs).

Build and Run

Prerequisites

• C++20 toolchain
• Meson + Ninja
• Qt6 (Core, Gui, Network, Widgets, OpenGL, OpenGLWidgets, Multimedia, MultimediaWidgets)
• Windows: DbgHelp (system library, used for crash reporting)

See docs/DEPENDENCIES.md for full dependency details and packaging toolchain requirements.

Windows Helper Build

pwsh -NoProfile -File scripts/meson_build.ps1

Manual Build (All Platforms)

meson setup builddir --backend ninja
meson compile -C builddir

Run

./builddir/src/pakfu
./builddir/src/pakfu --cli --help

Windows:

.\builddir\src\pakfu.exe
.\builddir\src\pakfu.exe --cli --help

CLI Quick Reference

Usage:

pakfu[.exe] --cli [options] <archive-or-folder>

Core actions:

• -l, --list : list entries.
• -i, --info : show archive summary.
• -x, --extract : extract entries (-o, --output <dir> optional).
• --check-updates : query GitHub Releases.

Installation profile actions:

• --list-game-installs
• --auto-detect-game-installs
• --select-game-install <selector>

Legacy aliases still accepted:

• --list-game-sets
• --auto-detect-game-sets
• --select-game-set <selector>

Update source overrides:

• --update-repo <owner/name>
• --update-channel <stable|beta|dev> (full releases only; prereleases are ignored)

Examples:

./builddir/src/pakfu --cli --info path/to/archive.pk3
./builddir/src/pakfu --cli --list path/to/archive.wad
./builddir/src/pakfu --cli --extract -o out_dir path/to/archive.resources
./builddir/src/pakfu --cli --check-updates
./builddir/src/pakfu --cli --list-game-installs
./builddir/src/pakfu --cli --auto-detect-game-installs
./builddir/src/pakfu --cli --select-game-install quake2

GUI Workflow

• Main modes:
  • Archive View
  • Image Viewer
  • Video Viewer
  • Audio Viewer
  • Model Viewer
• Opening behavior:
  • Opening a supported media/model file can launch its dedicated viewer window.
  • Opening an archive prompts: open directly, install a copy then open, or move to installation then open.
• Navigation:
  • In standalone viewers, mouse wheel and arrow keys cycle sibling files in the same folder.
  • Fullscreen toggles with F11, middle mouse, or platform fullscreen shortcut.
• Archive operations:
  • Drag-and-drop import/export across directories and tabs, plus file/folder drops from external applications.
  • Double-click nested container files to mount and browse in-place.
  • Multiple nested layers are supported.
  • File menu and context menu actions support Extract Selected, Extract All (archive views), and Convert Selected Assets....
• Safety:
  • Pure PAK Protector is enabled by default for official archives (read-only protection with Save As workflow).

Installations (Game Profiles)

PakFu stores per-game installation profiles with:

• default directories,
• palette preferences,
• launch settings (executable/arguments/working directory).

Behavior:

• If profiles exist, PakFu opens directly into Archive View.
• If none exist, the Installations dialog opens on startup.
• Auto-detection order: Steam -> GOG.com -> EOS.
• Auto-detection coverage includes Quake-family, Doom-family, Half-Life, SiN, RtCW/ET, Jedi Outcast/Academy, Elite Force titles, Heavy Metal: F.A.K.K.2, American McGee's Alice, Quake 4, Doom 3, Doom 3 BFG Edition, Prey, and Enemy Territory: Quake Wars.

Selector support:

• --select-game-install accepts UID, game key, or display name.
• Use --list-game-installs to enumerate current profiles and keys.

Updates and Releases

PakFu can check GitHub Releases at runtime and from CLI.

Build-time updater config:

• -Dgithub_repo=themuffinator/PakFu (default; see meson_options.txt)
• -Dupdate_channel=stable|beta|dev (default: stable; full releases only; see meson_options.txt)

Release automation:

• Nightly pipeline: .github/workflows/nightly.yml
• Channel auto-version pipeline: .github/workflows/auto_version.yml
• Manual rebuild pipeline: .github/workflows/release.yml

Release artifact naming contract:

• pakfu-<version>-windows-<arch>-installer.msi
• pakfu-<version>-windows-<arch>-portable.zip
• pakfu-<version>-macos-<arch>-installer.pkg
• pakfu-<version>-macos-<arch>-portable.zip
• pakfu-<version>-linux-<arch>-installer.AppImage
