What is a .VPK file?
VPK is a Valve Pak archive of game assets for Source-engine games. Created by Valve.
- Did you know
- Valve ships the content for games like Team Fortress 2 and Dota 2 in VPK packs.
- A VPK is split across several files - a <name>_dir.vpk index plus numbered archive chunks each limited to about 32 MB.
- VPK was first introduced in the Left 4 Dead engine branch and later backported to older Source titles.
- What Analyser reads
- Inspect game ROMs, patches and engine assets: iNES/NES2.0, Game Boy/Color/Advance, SNES, Nintendo DS/DSi, Nintendo 64, and Sega Genesis ROM headers (title, mapper, region, checksum); IPS/BPS/UPS/PPF patches; Doom WAD lumps; Minecraft NBT/schematics and Bedrock bundles; Aseprite sprites; Godot .pck; Quake/id Tech PAK/PK3; Source BSP/VPK/VTF/VMT; KTX/KTX2 textures; Tiled maps; LÖVE games; PICO-8 carts - plus MPQ, 3DS/Switch and Ren’Py/RPG Maker identification.
- Depth of analysis
- .VPK is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .VPK file
- Drag a .VPK file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
