A VDF file is a data file format used by Valve's Source game engine. It contains various kinds of game metadata, including data for resources, installation scripts, configuration scripts, and visualization elements.

VDF files can often be seen when installing games distributed through Valve's Steam game client, such as Half-Life 2 and Counter-Strike. The file features Valve's KeyValues format, which is a plain text format that saves key-value parameters in a tree hierarchy. The format is similar to JSON and YAML. While VDF files are meant to be used by the Valve Source game engine, you can open the files with a text editor to view the contents.

NOTE: You can view more information about Valve's KeyValues format on the KeyValues Wiki Page.
