About ValveResourceFormat
Source 2 Viewer, also known as ValveResourceFormat, is a set of tools for working with compiled asset files from Valve's Source 2 games. Its main job is to browse VPK archives, view and extract assets, and decompile them. The set includes a viewer application, a command line decompiler, and the ValveResourceFormat library. Valve does not provide Source 2 documentation, so the supported formats come from reverse engineering, and not all of them are fully supported.
Pricing is not clearly stated.
