GCFScape

GCFScape is a software tool created by Ryan Gregg that allows users to browse and extract the contents of Source Engine game files. These files are typically used in video games developed with the Source Engine, such as Half-Life, Team Fortress 2, and Portal. With GCFScape, users can easily explore the files used in these games and get a better understanding of their structure and content.

The software's user interface is simple, featuring a standard file browser that allows users to navigate through the contents of the game files. It also provides various options for searching and filtering through the game files, as well as for extracting specific files or entire folders to a location on the user's computer.

GCFScape is a free and open-source software tool that has been widely used by game developers and modders since its release in 2006. It is available for download on the developer's website as well as various third-party software distribution platforms.
