How to Open a VPK File

VPK is a file format specific to some games that run on the Source engine of game developer Valve. The VPK format was introduced with "Left 4 Dead," and has continued to be used in newer releases such as "Portal 2." People who create mods for Source games often need access to specific VPK files. In order to get inside a VPK file, you will need a program called GCFScape. GCFScape requires Microsoft .NET Framework to run.
